Socialist sales pitches like UBI always promote how you, the common plebeian, will have more money. They seldom address where that money will come from. Even when they do, it's a base appeal to envy about taking it by force from people richer than you. This is easy to sell because a smart person with the luck to be in the right place and time can make a lot of money under a capitalist system.
But it's unworkable, because under the socialist system being proposed, they never could have become that wealthy in the first place. Anyone who becomes the slightest bit wealthy will have it taken away by the system. The incentive to succeed is thus eliminated.
Therefore, the money necessary to keep the system moving - money created under capitalism - would never have been created in socialism.
Worse, what socialists never address is who will be the ones taking that money by force. All redistribution schemes require someone to do the redistributing. When pressed, the socialists will wave their hands and say "the state", but in the end, there's always a person. No matter who is selected for that job, it is human nature that the position will, given time, be filled by someone corrupt and power-mad.
