[Hammershaft]

It isn't a fantasy if the US and other high tax rate countries apply pressure in the form of holding at stake economic access at stake.

I'm not in favour of the corporate tax, I would rather have a high progressive consumption tax, a progressive inheritance tax, and a land value tax. (yes I recognize this will never happen...) That said, tax arbitrage across borders is the same kind of global coordination problem as climate policy across borders.

Accepting a race to the bottom and resigning to a climate catastrophe are not solutions; we need countries who want to fix these problems to band together and create carrots and sticks to incentivize misbehaving countries to join in.
