No, it’s really not - you’re either forgetting or are unaware of payroll taxes, insurance, etc. not to mention rent, electricity, capital expenses, and every other expense needed to run a business come out of that $1m.
No. In fact I run a bootstrapped SaaS business and am able to pay more than 7 employees on 1m. Do you have a source for your claims? My accountant can verify mine.
Some of your list is silly. My electricity bill is $25 per month. My rent is $800 per month. I choose a smart place to open a startup, not SF.
