> it's Bloomberg's money A large chunk of that money is subsidized by tax payers, as he would not keep the 1.8 Billion if he had bought a sports team or other vanity project that was not tax deductible. I am not saying spending taxpayer money to promote giving is a bad idea, but it is an expensive one that’s generally forgotten about.
I don't follow this line of reasoning. It's his money, not taxpayer money. If he simply held on to the money, he would not owe additional tax on it either. Perhaps it will eliminate his personal tax bill for 2018, but his yearly income is far less than $1.8B, and his tax bill is only a portion of his yearly income... the tax implications of this gift are only a small portion of the amount.
Even if he had 1.8 Billion in cash and ‘only’ got to deduct from his current tax bill that still means the US population is giving up money to support his cause.
Taxes are not about the government. They are a shared burden by tax payers and anyone paying less is increasing that burden for everyone else. The only way to reduce it is for the government to sped less money.
