$200k, including benefits, employment taxes, etc. is probably more like $150k in salary. It's not at all egregious for good programmers. I've had employees make near that in Ohio and have friends in the field who make considerably more. Also it's a budget, so I suspect it's intentionally padded to a small degree. While prices haven't converged on SV everywhere, it does have a ripple effect.
You're overestimating their final salary. Per-employee expenses are usually almost the salary all over again. Payroll taxes are a real bitch. It's probably closer to $110-$120k salary per employee.
I also make a fairly lower wage than the industry average since I'm not in SV, insurance rates don't increase proportionately with salary so if this is what I'm seeing at $75K/yr then at $200K/yr gross these employees are most certainly seeing at least $150K/yr in their salaries.
