That's $593M taxes on $1.34B earnings on exercising stock options...44% tax rate is pretty harsh!
For the US maybe. Income tax in the Netherlands (my country) in the top bracket is 52%. On the second hand, we have no capital gains tax so he might come out ahead when exercising options. On the third hand, we have a wealth tax of 1.2% on your entire capital above a certain floor (of about 20k) so he might not come out ahead in the end. It's always interesting to see the opinions of different cultures about how much…
Realize none of these numbers include the local, county, state, sales, and property taxes he pays.
At some point, theft becomes a more suitable word for it.
