That also seemed odd to me.

I think they are confusing a wealth tax with fair taxation.

The shown numbers seem to roughly correspond with what would be owed if they had paid fair capital gains tax over the past years. In other words, if all the tax loopholes were closed.

Bill Gates just didn’t have nearly the same amount of capital gains over the past few years compared to Elon and Jeff.

A wealth tax would tax then proportionally similar, so Jeff wouldn’t be paying 10x the tax that Bill G would pay.
