People who assign billionaires as being the living manifestation of greed are somehow quick to hand wave away "billionaires will move to protect their wealth".
> Look at what Texas has been doing to California.
What might that be? California is still at the forefront of every technological innovation this country is seeing while Texas is at the forefront of theocracy.
California may be seeing a smaller share of the world’s innovation in the past, but that hasn’t moved to Texas, it’s moved to China.
The point of being wealthy is that you don't have to care about shit like that. You can be taxed at 90% land still have more money than you could spend in a thousand lifetimes.
Until the early 1980s, the highest tax bracket was taxed at 70%, and before that even more.
It used to be that the US had unique ways of dealing with that, by virtue of its sheer size and dominance. But nowadays the ballon is leaking power from both ends, soft and hard.
You think people living in NYC, for example, the financial (and one of the major cultural capitals) of the entire world (not to mention all the other benefits of US residency) are going to bother with packing up their lives and moving overseas because the taxes are too high? Not to mention these people will still have obscene wealth in all likelihood.
Some might, but I don't think we should wring our hands over it.
Rather than worrying about "capital flight" let's instead imaging all the good that could come of us having a more more equal wealth and income distribution.
The effective income tax rate was still on the whole higher for the wealthy in the 20th century. Depending on where you put the percentile cutoff, I’m seeing peak-to-troughs between 5-20%.
And the reason most governments reduced the rate was because economists argued that the higher rate reduces economic activity so much that total tax revenue (collected by the government) is actually higher at the reduced rate. Look up the "Laffer curve".
Europe figured this out long ago and has a very broad tax base (aka higher taxes on the middle class) to fund their social welfare programs but somehow you never see that proposed as a solution by the middle class in the US...
The never come back bit solves the imaginary problem you mention.
