Why does nobody point out that in the event of an exit, an entrepreneur has control over the timing of their income? Sure, I suppose some subset of people who sold an inordinate amount of stock in 2012 now have to pay more, but how much more? Doing the math, it seems this tax likely increases ones tax bill by roughly 5%.

If you believe a 5% decrease in take-home proceeds from successful outcomes will stop entrepreneurship, I've got some swampland in Florida to sell you.
