Corporations taking over side hustles seems to be screwing over people, since they take such a large cut and flood the market for that hustle.
But the ones I’ve personally seen people do that work pretty well (in USA) are:
Stay at home mom watching another kid (legally dubious depending on state/situation. But I ain’t no narc.)
A neighbor of my mom’s sends out a menu saying what she plans on cooking each night for that week, and for $X will deliver you some as well (Legal in Utah due to special laws, other states could be dubious. )
People who go pick up free furniture that is pretty trashed, and then refurbishes it and sells it. Or people with trucks who are like “Will deliver furniture for $30 in X area” is also pretty life saver for people without cars/trucks. Was able to get a super cheap/nice coach because of this.
People who just flip free stuff or stuff from thrift stores without doing any improvements annoy me greatly though. We broke and you’re just driving up the price!
None of these generate a ton of cash, but I like that they take very little up front cost, aren’t disruptive, and mostly take labor.
So what side hustles have you seen work out?
Churning. The art of spending money in a circle using accounts that offer rewards.
I knew a guy who had like 50 credit cards and 25 bank accounts. He could move money in circles all month, and get like $100k/year in cash back rewards on top of his $100k/year job. His credit report said he spent $8M a year on credit cards. His credit score was 845.
He also pretty much flew for free, and he flew all the time. There were a few mileage programs in his little scheme.
As far as I can tell, 100% legal. The banks just make frequent changes to their offerings to make it hard to do.
