MAJOR CAVEATS
  • •Static vs dynamic scoring contested: OBR uses static, but 2024-25 receipts below forecast after tax rises
  • •Laffer curve position uncertain: record millionaire exodus (UK now global leader) and non-dom flight suggest behavioural response stronger than models predict
  • •Elasticity assumptions vary widely: academic models (0.1-0.3) vs observed capital flight response
  • •International evidence mixed: Ireland corporate tax success, UK 50p rate underperformed, Kansas cuts failed (context-dependent)
  • •Transition costs real: static cost £40-50bn/yr requires offsetting measures or borrowing
  • •Counter-evidence: UK highest tax burden since 1948 correlates with stagnant growth, not revenue maximisation

-£10.0bn
MAJOR CAVEATS
  • •Relative poverty measure misleading: pensioners have highest median wealth of any age group (£500k+ for 65-74s)
  • •Triple lock has created massive intergenerational transfer: pensioners only group with rising real incomes 2010-2024
  • •Pension credit uptake only ~66% - reform should include automatic enrolment for poorest pensioners
  • •Political feasibility is genuine constraint: 75% pensioner turnout vs 47% under-30s creates democratic distortion
  • •Demand effects likely overstated: pensioners have low debt, high assets, can draw down wealth
  • •Status quo cost: triple lock projected to consume entire fiscal headroom growth to 2070
  • •Reform sequencing matters: increase pension credit take-up before or alongside triple lock changes

MAJOR CAVEATS
  • •Climate models have wide uncertainty ranges; damage estimates vary by 10x depending on discount rate assumptions
  • •UK is 1% of global emissions - unilateral action has minimal climate impact but large economic cost
  • •CCC/OBR models assume global coordination that is not occurring - China/India emissions rising
  • •EU CBAM applies to some exports, but UK already deindustrialised - limited remaining exposure
  • •Energy costs already 40-60% above EU competitors - further divergence accelerates deindustrialisation
  • •Stranded asset argument applies both ways: £200bn+ sunk in intermittent renewables if nuclear/gas prove optimal
  • •Track record: Net Zero policies to date have not reduced global emissions, only offshored UK production
  • •Adaptation may prove more cost-effective than mitigation for 1% emitter

MAJOR CAVEATS
  • •Certainty of punishment matters more than severity - but UK has 6% charge rate, undermining both
  • •UK incarceration rate (130/100k) far below US (500+) - diminishing returns argument less applicable
  • •Rehabilitation vs incapacitation: contested evidence, but early release schemes have increased reoffending
  • •Court digitisation risk real: HMCTS Common Platform has had significant problems
  • •Prison capacity constraint genuine: 99% occupancy means early release regardless of policy intent
  • •Police solve rate (6%) is the binding constraint - more prison places useless without arrests
  • •"Root causes" framing often becomes excuse for inaction; enforcement and social policy not mutually exclusive

MAJOR CAVEATS
  • •Economic impact highly uncertain - both regulation costs and deregulation benefits contested
  • •UK already below US on speech protections; deregulation moves toward international norm, not outlier
  • •Platform self-regulation may continue regardless of law (advertiser pressure)
  • •Current restrictions have not prevented social harms (Southport riots occurred despite Online Safety Act)
  • •Counter-argument: coordination costs of harmful content are real but hard to quantify
  • •International advertisers may prefer clear rules to ambiguous liability
  • •Track record of speech restrictions: 9,700 arrests in 2024 yet Article 19 downgraded UK
  • •US speech regime correlates with world-leading tech sector and research output

MAJOR CAVEATS
  • •Track record: UK net migration hit record 900k+ despite claiming "control" - selection system not working
  • •Points systems require enforcement: Australia deports overstayers, UK does not
  • •Low-skill shortage claims contested: wages in social care/agriculture suppressed by cheap labour availability
  • •Net fiscal contribution varies enormously by origin, skill level, and time horizon - averages mislead
  • •Family reunion and asylum are separate from economic migration - conflating them confuses policy
  • •Housing/infrastructure constraints may limit absorption capacity regardless of skill level

MAJOR CAVEATS
  • •UK planning uniquely slow: 4-7 years for major projects vs 18 months in Japan, 2 years in Germany
  • •Previous reforms captured by incumbents: Planning Act 2008 added process without removing obstacles
  • •Judicial review reform contested but UK abuse rate far exceeds other democracies
  • •NIMBYism economically rational for homeowners - reform requires changing incentive structure not just rules
  • •Construction capacity genuine constraint: skills shortage, materials costs, would limit short-term gains
  • •Environmental assessment: 50 separate requirements vs single process in most countries - consolidation not abolition
  • •HS2 failure was management/scope creep, not planning speed - wrong lesson to draw

⟷

+£25.0bn
MAJOR CAVEATS
  • •AI safety concerns real but often conflated with bias/fairness concerns that are more contested
  • •Brussels Effect limited: EU AI Act primarily affects EU-deployed systems, not global development
  • •UK already lighter-touch than EU - question is whether to go further toward US approach
  • •Compute and talent are genuine constraints: £14bn infrastructure plan addresses compute, talent needs visa reform
  • •"Bad actors" argument proves too much - applies to all technology, not specific to AI
  • •Skills shortage is binding constraint but can be addressed in parallel with regulatory approach
  • •Track record: UK tech sector successful precisely where regulation is lightest (fintech, gaming)

MAJOR CAVEATS
  • •Benefit-cost ratios of UK regulations rarely evaluated post-implementation; assumed benefits often not realised
  • •Regulatory uncertainty is real risk - clear sunset process essential to avoid investment freeze
  • •International comparison: UK regulatory burden heavier than US, Singapore; lighter than EU
  • •Catastrophic failure risk real but rare; status quo also has costs (Grenfell was regulatory failure, not absence)
  • •Externalities cut both ways: regulation can create negative externalities (housing shortage, energy costs)
  • •Track record: UK regulatory state has grown continuously since 1990s while growth has stagnated

⟷

+£30.0bn
MAJOR CAVEATS
  • •UK deindustrialisation was policy choice (energy costs, planning, skills) not inevitable market outcome
  • •Services focus has delivered stagnant productivity since 2008 - "comparative advantage" is circular argument
  • •"Picking winners" critique applies to all state action; question is whether current approach works (it doesnt)
  • •US IRA/EU subsidies are real competitors but UK can focus on niches, not match scale
  • •Energy costs 40-60% above EU is solvable policy problem, not fixed constraint
  • •Labour costs argument ignores productivity: Germany has higher wages AND more manufacturing
  • •Brexit friction real but UK can also negotiate FTAs with faster-growing markets
  • •Taiwan/Korea/Singapore success required state capacity UK currently lacks - rebuild that first
