Summary
« Program of systemic rupture: 6th Republic via Constituent Assembly, ecological planning enshrined in a constitutional « règle verte », €200bn investment plan, restoration of retirement at 60 with 40 contribution years, autonomy guarantee at the poverty threshold (€1216), nationalisations of strategic public poles (energy, transport, banking, pharmaceuticals, armament), 14-bracket income tax, withdrawal from NATO integrated command and explicit disobedience to European treaties incompatible with these objectives. The six models converge on a positioning at the economic and ecological far-left with a deep institutional overhaul; they diverge most on the magnitude of the intergenerational transfer, the long-term budgetary sustainability of the pension system, and the emissions trajectory under nuclear phase-out. »
Consensus 78% — 6 model(s)
Strengths
  • Greenhouse-gas emissions and ecological debt
  • Concentration of executive power and bypassing of Parliament
  • Income poverty and precarity among young people / unemployed
Weaknesses
  • Compliance with the European budgetary and monetary framework
  • Structural cost of the pay-as-you-go pension system
  • Dependence on critical raw materials for renewables
Notable gaps
  • Electricity-supply security and industrialisation of the 100% renewable mix on the 2050 horizon
  • Legal and political modalities for implementing Plan A (treaty renegotiation) in the face of likely refusal by European partners
  • Long-term actuarial sustainability of the retirement-at-60 system in the face of demographic ageing
Political positioning

Social / Cultural⚡ Disagreement ±2
EELV (2022)Macron (2017)LR (2022)Zemmour (2022)
Modal: -4claude-opus-4-7 — position -3
Constitutionalising abortion, assisted dying, gender self-determination for minors with one-parent consent, full birthright citizenship, and voting rights for foreign residents in local elections place the program firmly progressive but within the recognisable French left tradition rather than at an extreme pole.
deepseek — position -5
The program includes very advanced societal measures on gender, drugs, end of life, foreigners' rights, and anti-racism, unambiguously.
mistral-le-chat-2026-04-25 — position -3
The program radicalises positions on individual rights (abortion, euthanasia, LGBTQIA+ rights), child protection, and the fight against discrimination, but remains less radical than anti-system movements.

Sovereignty⚡ Disagreement ±1
Glucksmann / Place publiqueMacron (2017)LR (2022)RN (2022)
Modal: 3claude-opus-4-7 — position 2
The Plan A/Plan B EU strategy explicitly elevates national constitutional norms above EU law and commits to unilateral disobedience — operationally a sovereigntist program. NATO withdrawal and ecological protectionism reinforce this, but the multilateral, UN-centric register and refusal of identitarian framing keep it below the high-sovereigntist anchor.
gemini-3-pro — position 2
Advocates ecological protectionism, exiting NATO command, and disobedience to EU treaties, asserting strong national independence — but from an altermondialist rather than nationalist register.

Analysis by domain
Intergenerational impact

Estimated net effect of the programme on each domain, across three budgetary horizons. Scores are ordinal (−3 to +3) and measure the direction of impact, not its desirability. Cohort labels are approximate narrative anchors that imperfectly cover the calendar horizons.
