I hate that this has happened. The Bay Area used to be a place where working for the big, shiny company that makes your parents happy wasn't prestigious. It was safe. But taking a risk and starting something new was admired. The present state of affairs reminds me of Wall Street.
The tech industry, despite its shortcomings, is vastly superior to Wall Street in that regard. It's still a meritocracy above all else.
Plenty of smart people break into tech after doing something else for a few years. If you want to go into investment banking, you better come from a consulting or have already been working in finance. Your only last bastion of hope is to get an MBA and then join the rat race.
