>>You can get an apartment for $500. Health Insurance is $30, utilities $200
Right off the bat, you're not "getting an apartment for $500." MAYBE you can find someone trustworthy who can rent you a bedroom for $500/month in some cities but:
As of 2020, monthly rent averaged $1,164 nationwide; median rent is $1,104.
Also, you need first month's rent ($500), security deposit ($500-$1000), utility deposit ($50 - $500), and sometimes last month's rent ($500).
So now we're talking a few grand. Better hope you spent the past three months working that guaranteed-40-hours/week minimum wage job without spending a single penny of your wages!
I also hope that your job is very close to your new apartment because you're going to need to spend a LOT of time chasing all the benefits that you seem to think are easily handed out and you don't have money for transit. Nope, you can't afford to take a whole day off work to wait in line for a free transit pass -- after all, you're going to spend $700 of this month's $900 income on housing and utilities!
At least make up numbers from this century if you're going to pull this Horatio Alger stuff :-)
