The weird psychology thing is while you aren't concerned about billionaires you are very concerned that nobody gets over on you. Why should people who don't work get a UBI? Why should people who make minimum wage get a living wage? Why should we interfere with the market when it sets prices for labor?
This paranoia that someone somewhere is getting something for nothing is the hallmark of the Conservative Mind. Contrary to your explanation for why you don't afflict the comfortable, you are very concerned when people try to comfort the afflicted. You come across as if being selfish is the normal mode of human behavior -- it isn't, it's weird. People try to help each other. When you say "what the rich have is their business, but what the poor have is MY business," you are being the archetypical conservative.
I'm not concerned about people "getting over on me."
With respect to UBI, I don't believe paying people to do nothing is a good or smart allocation of resources. If you pay people to do nothing, people will do nothing.
We actually
need people to work in this country, in this world. We collectively benefit by that.
With respect to the minimum wage, I have always believed that we need low paying, entry level jobs. They serve a purpose. They teach people what it means to be an employee, and they are jobs that an employer can afford to offer.
My very first job, outside of mowing yards, was when I was a kid and was hired to wash dishes at a local steakhouse. Minimum wage, which as I recall was barely $2/hr. I remember that I'd work maybe a six hour shift and barely make more than $10.
Now, could I live on that? Of course not. I never expected to. I didn't stand there, scalding my hands, thinking that I'd found my life's work, now all I need to do is find a wife and start a family.
The reason I took that job was so that when it came time to apply for the next job, a higher paying job, I had something to show the future employer.
Does that job exist if the restaurant owner had to pay me enough money to cover food, shelter, clothing and all of the other expenses necessary to be a "livable wage?" No chance. But we both benefited. He got his dishes cleaned and I gained experience.
