I think that sort of depends on your perspective. Some critics of UBI would say it's basically a scheme to keep a capitalist system and a ruling class in place that we'd be better off doing away with.
This is literally the first time I've seen someone call UB I a capitalist scheme, as the absolute most of these capitalists would call UBI a socialistic measure.
I know it sounds odd, but the idea is that while it is a socialist program, it actually helps maintain a capitalist system by preventing that systems failures from leading to it's demise. A UBI paid for with a tax system similar to our current one wouldn't really harm the ultra rich much, it would be paid for by the middle class and wealthier people who still work for a living, rather than just sitting on a giant mountain of cash and collecting interest.
Edit: plus, if everyone views it as socialism, and then they eventually get it 20 years from now, maybe that will keep them from pursuing the real thing. Although I'm getting to be a bit of a paranoid conspiracy theorist with that line of reasoning.
