Because the question is dumb. If you ask 10 people you might get 10 different answers. I know people who left for sunshine and warmer weather, others to be near their kids, etc. People come and go. Many people leave NY for CA and vice versa. Many go south to FL or TX. I know people who have moved from the south to NYS too. Many leave NYC and CA due to high rents because of high housing demand.
There are advantages and disadvantages to wherever you choose to live. MAGA likes to paint Dem states as unlivable hell holes. Anything that isn’t Trump/MAGA approved is the worst thing imaginable. It’s all part of the cult mentality. I know plenty of people in NYS who would never move to TX or FL if you paid them. If people don’t like where they live, they should run for office or move.
