I'm posting this in good faith, both out of curiosity and self interest. But up front I'll say that I'm not interested in scams, schemes, or get-rich-quick stuff.

I work full time as a teacher, but ever since we had a baby, my wife and I are just barely breaking even financially. Not struggling, but $4k/year would make a massive difference in our lives.

It seems like I'm stuck in this spot where getting a low wage job after school hours isn't even worth the time missed with my family, considering how awful the pay is. Summer work is tough because it has to justify the extra daycare expenses, and again, it's so much missed time with family for such a low reward. Higher paying gigs don't seem as interested in seasonal help from what I've encountered so far.

For the record, I'm not really interested in crypto or casino bonus schemes. I also don't have enough to invest right now to truly put investing over the edge into a meaningful return.

What are some low-risk/low-investment/low-reward side hustles?

This question has been going through my head for quite some time. UBI has been talked about quite a bit now, and usually the question is if it should be introduced and if yes, how much should everyone get?

But how would you stop UBI from inflating the economy? If everyone suddenly gets 1000€/month purely because they exist, how do you stop rent from suddenly going up 1000€/month? How do you stop it from going up gradually?
