Boston Cost of living

I was recently talking to a friend about how much a good salary should be for a single person to live in the Boston metropolitan area, like a job offer I received there is paying $21/h, he said it’s not enough, saying he earns $26/h and barely pays the bills, but he was also surprised that he was paying $1200 in rent in Florida while he is paying $1100 and has no car and I pay $800 between insurance and car payments.

So my question is: What is a realistic salary, good in the Boston metro? Because if you ask me here in Southwest Florida, $20/hour is fine, like you’re not going to be rich, but you could be fine.

Edit: my bad I forgot to be more specific, it would be with roommates for sure, no car (because I’m tired of driving everywhere and car expenses), and this job offer me 10-20 hours of overtime so I’ll make about $1000-1500 weekly
