Also, I think many menial jobs could be made a lot more pleasant with only a slight cut in productivity.
Hurray for qualify of life!
And since after UBI every dollar after taxes goes to luxuries, a low income provides a lot more luxuries than it does before UBI, so it's actually a lot more appealing to work -- you see the benefits directly.
Then people start advocating for universal housing and universal food.
Food: Foods are commodities, meaning that the price is the marginal cost. The price of a bushel of rice is set by the buyer, not the seller.
Which is exactly what has happened (in the US at least) as people received mini-UBI called "stimulus checks" and their bosses got PPP "loans" (that didn't need to be paid back)
People will bid up apartments because they have more money.
Why wouldn't regular minimum wage workers just be homeless and spend their money on luxuries if this was the case?
What use is buying the new video game if you don't have a place to put a TV to play it on?
UBI would be a subsidy to landlords and supermarkets; who would cream off a profit.
I think there would be a massive pressure to raise minimum wage.
Why would you work for $7.50 an hour and pay $1 in taxes - spending the majority of your day to make ~$50 - that doesn't buy much - and you don't have much time to spend it anyway?
When your options are either do that or be homeless and hungry - most people opt for work.
But when you have other options - spending your entire day to make $50 seems dramatically less appealing.
