Sergey Brin has an estimated net worth of $232.3 billion, which means the one-off payment of 5% would be $11.6 billion – approximately 258 times his $45 million in contributions. Such a law would also set a precedent for further taxation of billionaires once it obviously works. Donating may also encourage other billionaires to donate because it signals the strengthening of the side opposed to the bill.
So from a purely self-interested, sociopathic perspective, this is easily a worthwhile investment.
I also conduct warfare like a broken simulated annealing algorithm.
