Earlier quoted context omitted.
For a single person, you'll hit that tax bracket after more than $500,000 in income. This is an absolutely enormous amount of money - roughly 10x the median income. I have absolutely zero problem with income beyond this amount being taxed at 50%. I make around $600,000. My effective federal tax rate is in the low-mid 20s. I'd have to make way way way more money for my effective federal + state rates to approach 50%.
What about sales tax, VAT, fuel levies, consumption taxes, gift taxes, inheritance taxes, etc. Your state or country may not have all of the above. But they are all there to tax you to ridiculous amounts but not at the "start". Same goes for withholding or "Pay as you earn" taxes which serve to not let you see how much taxes you are paying. No one will be happy if more than half their labour is taken from then. We ca…
Sales tax adds less than 1% to my overall effective tax rate. Sales taxes are disproportionately low for high earners because high earners save larger portions of their income rather than spending it.
Gift and inheritance taxes don't start until eight figures. Not exactly something I'm especially worried about.

You can adjust your W4. The very wealthy also have considerably more flexibility with withholding since less of their income is W2 income from an employer.
> No one will be happy if more than half their labour is taken from then.
If I made the 7+ figures annually or whatever I needed to approach 50% effective taxation I'd be pretty damn happy. If my taxes were raised considerably without a change in my income it wouldn't really change my life either. I'd just retire early a little bit later.

Extremely high earners who have very high effective tax rates have some options available to them. They can change careers or work less to reduce their income. They'd just earn an income that was more comparable to the typical worker. Or they could stop working entirely - extremely high earners have plenty of opportunity to save enough money that they could live off a typical budget indefinitely using their savings. Or they can advocate politically for policies they prefer - even by spending their money to influence elections via nearly unlimited and unbounded political contributions.
Slaves can be arrested, tortured, and murdered for fleeing their captors. Heck, they can be tortured and murdered pretty much for no reason whatsoever. They can be raped and forced to bear their children of their captors. Their children (whether conceived through consent or through rape) can be permanently taken from them and also forced into slavery. They can have literacy denied to them. They can be worked to the bone in extreme conditions. And all this for a fat zero dollars in income over their entire lives.
So I'd say that there are more than "a few steps" between these things.
