Considering how skewed tax participation is, this would be a very one sided view. Just tax the top 49% more, no matter what's their current level of taxation, and redistribute to the lower 51%. It'll always make this criteria look like a success.

Problem is, this creates systemic effects. If you look longer term, a society that does this will end up a lot poorer than one that doesn't. Even for the bottom 51% you were optimizing. Because there are two variables to control: the redistribution, and the actual productivity. If you just focus on splitting wealth, you stop growing wealth.

Growing wealth on the other hand will make everybody richer, including the botton 51%. Simply participating in a richer economy has advantages. Plus the smaller redistribution percentage will actually end up bigger in absolute terms.

Got data to back that up?

(On the serious level, I'm really curious; But on the polemic level I'll call BS - I highly doubt there ever was such a period in any capitalist country ever)
