That's just crazy talk, there are PLENTY of companies to work for. If you're talking about big tech companies sure, but for every big tech company, there are zillions of other companies that require big tech people. I work for a company that is complete unrelated to my field. I get paid well, I travel the world to their ninety offices, and my house is only a five minute commute.
The northeast, NY/NJ/PA/DE/DC/MD area has a vibrant economy aplenty. Within a 3 hour radius, there's virtually an unlimited amount of jobs across a ton of industries.
The places that scare me are places like Chicago & Atlanta. Outside of Chicago, there's virtually nothing. Outside of Atlanta, it's the same, which usually means moving across the country for something.
I lived on the east coast for years, and I'd happily move back in a heartbeat, but I'd be a nervous wreck every time it looked like another downturn was coming and I might have to scramble to find another job.
