This is the best summary I could come up with:

If levied, the sum would be equivalent to only 2% of the nearly $13 trillion in wealth owned by the 2,700 billionaires globally, the research group hosted at the Paris School of Economics said.

“In our view, this is difficult to justify because it risks to undermine the sustainability of tax systems and the social acceptability of taxation,” the observatory’s director Gabriel Zucman told journalists.

U.S. President Joe Biden’s 2024 budget included plans for a 25% minimum tax on the wealthiest 0.01%, but that proposal has since fallen by the wayside with lawmakers in Washington preoccupied with government shutdown threats and looming funding deadlines.

Though a coordinated international push to tax billionaires could take years, the Observatory pointed to the example of governments’ success in all but ending bank secrecy and reducing opportunities for multinationals to shift profits to low-tax countries.

The 2018 launch of automatic sharing of account information has reduced the amount of wealth held in offshore tax havens by a factor of three, the observatory estimated.

For example the rich increasingly park wealth in real estate instead of offshore accounts while companies can exploit loopholes in the 15% corporate tax minimum.

250 billion for what? Governments are horribly inefficient and many of their employees operate with the thought “not my money not my problem I can just spend it however I want”

Billionaires getting taxed more only treats a symptom and not the root cause. Their corporations should be broken up, competition should be stimulated, shareholders should demand limits on exec bonuses and the executive pay should be limited to a reasonable ratio of exec to lowest paid employee pay.

That would make things better and money in the government should be spent more appropriately.
