You could kill them all and take every penny they own and it still wouldn't solve the problem.

That presumes billionaires have no agency and aren't at all responsible for the world we live in. It assumes they don't spend millions on political ads and lobbyists and politicians. That they aren't responsible for the actions their companies take. That private equity does the things they do and the billionaires funding them don't have any say in what they do. It assumes billionaires' companies aren't also responsible for how the world is going, and that they don't meeting with other billionaires and make plans together.

None of that matters for the French national spending and budget issue.

They arent the ones driving up pensions for the retired, or instituting the anti-growth policies.

Like I said, kill every single one and the problem would still be there.

Where is your evidence that they're "giving all the tax money to billionaires", comrade?

So once you've milked the 43 French billionaires to extend French spending by 2.5 years or so (this assumes you extract 100% of their wealth into actual liquidity), what's your plan for year 3?
