Taxes should exist to fund the needs of the government, not to punish people. Confiscating incomes and gains as described in this thread (punitively) would destroy working capital and investment capital which would would lead to lower incomes for everyone, higher unemployment, and in essence make everyone poorer.

It's not punitive confiscation. It's taxes to fund the decided needs of society, where the needs are established using the mechanisms of government (as flawed or otherwise as they might be).

This seems like the reciprocal of the now completely debunked claim "reducing taxes would increas working capital and investment capital which will lead to higher incomes for everyone".
There are so many bundled assumptions in your claim here, most notably that higher incomes require private investment. There's no particular evidence that this is true (although there is a lot of hand-waving "common sense" pronouncements from certain parts of the political landscape designed to us think that it is obvious).
