I don't know anyone making $200K outside a bank. Senior salaries in NYC (which is a high-price/high-salary city) tend to run around $150K, give or take 20% (for 10+ years of experience, not someone with 2.5 years experience and a "senior" title).
At startups maybe, senior developers at established companies earn more like 300k+.
AFAIK, only Google and Facebook have fairly sizeable engineering offices here and pay that much.
Even the large financial institutions pay most of their engineers less than 200k, maybe around 150k.
I've heard of "quants" (engineers / mathematicians) who sit at the trading desks making bank, but that was in the days of when trading actually made a ton of money, and I have to yet meet someone in person to ask them how much they made.
