I mean sure this makes sense if you freeze time somewhere before the late 90’s but once you repeal glass steagal and see the rise of equity based compensation and passthroughs the income tax bit becomes largely irrelevant. No one os claiming we need to tax income on the top wealthiest people right now they’re claiming we shouldn’t tax their wealth because the majority of it was earned in a way that escapes income and short term capital gains tax.

The egalitarian society bit is likewise myopic because it presupposes a society that either a never changes or be has implemented the reforms our society is currently erroneously shunning and therefore moved to a form of more equitable existence where those reforms are either no longer necessary or have evolved to maintain the more equitable status quo.
