UBI isn't a savior. UBI still requires that people, you know, pay taxes. If 30-40% of people have no income and are completely dependent upon the government, then you have slavery 2.0 (3.0?) and you will end up creating a worse, classed society than you had before: the ones receiving vs. those who pay for what everyone else gets.
Or the government just prints money and money doesn't mean anything anymore because the government controls what it is worth.
Either way things are not good, but they are not good in a way that just means people starve, it means that the foundation of society is crumbling.
