Work As Crossing Guard Or Garbage Man?

Crossing guard is part time, barely above minimum wage, contractual obligation to work during school months, and gotta pass a background check to make sure I'm not a pedophile. Garbage man is full time, moderately above minimum wage with chance for more pay over time, essential job so can never be laid off if economy worsens, and very physically demanding. However though, crossing guard being part time and super easy to do allows me enough time and effort to further dedicate the next few months for my startup to take off, whereas garbage man I can finally achieve financial independence in a short time frame (months instead of years if I relied on startup) and I don't have to be at home with my weird family.

Of course, it's up to the employers if they wanna hire me or not based on available positions and how fucked or easy the hiring process is, and if I can be offered to work as either, I still don't know which to choose. I've checked other public sector jobs in my city, and sadly they're not eligible for me as I either lack the necessary credentials and/or the relevant work experience (so volunteering, freelancing, transferrable, etc don't count). I basically gave up on applying for private sector jobs, since I've applied to probably thousands at this point over the past decade with almost no success besides some interviews that got me nowhere. And also because the economy is so fucking terrible, along with employers not wanting to hire full time positions nor provide benefits nor pay a liveable wage.
