I've said it here many times. The average American cannot not outthink the left, just as you cannot out think a criminal. Their brains are simply wired differently. This stunt by Mandami and the Governor isn't about taxing the wealthy. It's about keeping wealthy people from fleeing the city and losing that tax revenue. They can no longer flee the state and it's heavy tax burden. If someone wealthy kept a home in NYC, they'll get taxed even if they don't live in the state. If they sell the home, whoever buys it will know full well he'll have to live there and it can't be a second home, thus guaranteeing a tax base for NYC.
In addition, if you're going to sell an expensive residence in NY, your asking price just went down because some people just won't buy it only to get taxed if they don't live there. It's a scam and could only be thought of and imagined by a criminal mind.
