Something tells me that many people won't pay those 16 billion and will move to a different place instead. NYSE isn't the only stocks market in the USA.
"Good riddance," you say, waving goodbye to all the Wall Street based jobs that pay Wall Street income tax to support universal pre-K in the Bronx. "We don't need their kind around here anyway ruining society" you say, as the MTA makes overnight service cuts permanent for lack of funding.
also, just to add. The Stock Transfer Tax started in 1909. They were paying until the 80s when the state started rebating it at 100%. Its is a 0.5% sales tax on the value of stock trades, 0.1% on debt and 0.005% on derivatives. The NYSE was doing fine when everyone was paying it.
