Not competitive because you still have to account for quality of life, working on site with no remote option, working evenings, nights, and weekends, general riskiness of being around drunk/high people, etc.
Of course you may not have had to study as hard, so your quality of life as a young person might have been better, but bartending is not secure income for life either.
Either way, the easiest way to look at it is, do parents tell their kids to aspire to become bartenders?
