I think people are still caught up in the "if you can make it there, you can make it, anywhere" mystique of NY.
But if you come from a suburban area in Virginia, where you had quality square footage, then realize you have to bust your *** to share a matchbox with your old frat bro, you might not stick around for the long haul.
There were 2 people who used to work in my office in NY. Dude from Virgina. Girl from Baltimore. Got together. Had kids. Moved to LA.
I think those numbers can be a bit skewed if you take into account that some of those people moving from NY to LA may are not actually native NYers.
Meanwhile, my wife and I are native NYers. Had kids. Bought a 3 bedroom in BK. And wouldn't change a thing.
I'll still take the subway over driving every day.
And I'll respectfully disagree with food and scenery being better in LA. Different I would accept. But certainly not better.
Weather maybe, but I like the snow. "That which does not kill us......"
But it's all good. I like NY more than LA. Some people like LA more than NY. I'm in LA often and always love my time there.
What is so fascinating is how much non NYers talk (usually not in a positve fashion) about NY
