> we would also have to lean more on corporate and consumption taxes rather than taxes around employment which would also make employment easier
I think the only way forward is wealth tax. Rich accumulated so much wealth already, that they don't need to put it to profitable businesses.
Wealth taxes require liquidating investments early and don’t promote good practices, especially if they are applied broadly. I would opt for a tax on loans instead (you have to prepay tax on loans that use investments as collateral and no more step up in basis on death).
