The USA is better at playing the zero-sum game of where to begin a business. Zero-sum because many businesses are winner-takes-all and the country that business starts-up in is the one that wins.
Business founders are greedy (almost by definition), and a country needs to think what marginally motivates a founder to keep on going (or to founding 2nd/3rd business).
Hate Meta, or even hate Zuckerberg, but the USA is winning export earnings from the rest of the world because of Meta (and likewise other billionaire companies).
On the third foot, I'm guessing Zuckerberg has other motivations than more dollars?
The game isn't equitable, and the wealth disparity is heinous, and perhaps even the products are despicable. However everyone in the USA is living off the back of that wealth coming into the country.
It is really noticable in New Zealand where top marginal rate is 39% and GST (sales tax) is 15%. Why work an hour to bring in in a dollar to NZ when you get less than 50 cents (after all the other taxes). Our left parties want to tax wealth at 50%+ (if 2% wealth tax and drawdown of 4% ). Invisible inflation makes the taxation much much higher.
A wealth tax of 1% sounds trivial, but it isn't when compared to risk-free returns after drawdowns.
Unfortunately most voters are not founders, so they don't understand marginal motivation. And voters don't understand who brings money into the country. Voters just want increasing amounts of money spent, and politicians cater to them.
If anyone here is a game mechanics designer, what do you most notice about the motivation of taxing wealth?
