Consumption yes. But how do you get to 70-80% for reinvesting? Corporate taxes are 20%, dividend taxes 30% on remaining 80? That gets you to 44% net tax. From gross to net. Income taxes are higher but still not 70-80%?

I agree income taxes are high throughout most of Western Europe, but the way to grow wealth is by acquiring assets that can grow without having to sell them and pay taxes.

An investment fund (or a property) can often grow for a long time and throw off cashflows that are taxed more efficiently. So can a business where you build up value in the equity. Cashflow keeps the lights on, but equity (even in a small business) builds wealth.
