We need a universal basic income because so that we no longer align our actions primarily with economic interests.
Anyone who can live on a basic income no longer needs to base their actions primarily on economic interests and can do what they think is right and good. Even those who continue to do wage labor no longer have to align themselves so closely with the interests of their employer, because it is much easier to quit at any time.
Many people no longer notice how much everything in our world is subordinated to economic interests. In many articles by journalists it should be noted that many paragraphs have no content and are only intended to fill the paper. The associated headlines are usually clickbait. Not only newspapers and media are affected, but also our entire culture. Adorno analyzed this development well. He talks about the cultural industry.
As Adorno famously said: “There is no right life in the wrong one.”
But at least, a basic income would be a good way to counteract this and create emancipatory spaces where profit is no longer the motivation for our actions.
