I'm with you on the opportunity cost of money but I don't see how it has anything to do with what we are discussing.
> The economics of software are simply different. Someone good enough to start a business that brings in $10-20K MRR and barely survive is almost certainly good enough to get hired and paid $200K+ by any number of companies. If you're not going big or going home, it doesn't make sense to do a software startup these days.
This is not true at all. There are tons of FAANG engineers plotting their exit to start their own business for the reasons of freedom and impact. It's not just about the money. Also, if you can reach $10-20k MRR—that's a lot more scalable than your salary at a company ever would be.
Don't confound entrepreneurship solely as a vehicle for getting rich.
