$1K in insurance (health / renters / home). Net $48K

Not bad. But you can see how bay area cost of living can quickly erode income.Add kids, dependents, cars, transportation, day care, private schools... and it's a net wash (or possibly even net negative with more debt).
[EDIT: If we're getting precise here, the effective tax is 38.18% before deductions. The point being that $150K yr is near the poverty line in bay area. $200K is barely enough to survive. $300K is what a FAANG will pay 90 percentile Engineers to ensure they're comfortable]
