In other words, people want to be slaves.
The Universal Basic Income would mean everyone was a slave to the government. If they don’t like your religion, politics or skin color they’d give you less.
It would ruin education, after all why study to educate yourself if you’re going to get paid anyway? This would add to the power that the super wealthy elite have over the masses because after a generation or two there would be nobody with the skills to overthrow them even if they wanted too.
Evil, evil, evil, the idea is simply evil.
