It's fucking retarded and anyone who supports it doesn't understand the slightest thing about economy or human nature. What happens when an ever growing portion of society are useless parasites who have never worked, never will work, know no one that works and their great-grandfather was the last person in their family with a job? I'll tell you exactly what happens, you get a steadily growing underclass of literally useless people who has one singular political issue. Increase the size of the base income and blame the oppressive "worker elitists" for everything wrong in their life. Modern society alone is not sustainable, with the US alone having trillions of unfounded liabilities. And this system would certainly not be.
