"Make work drudgery" will still need to be be done by someone.
>its true even some engineering, doctoring, lawyering (wait that happened already) jobs will be automated too, and those folks will find the UBI useful.
How?! How will they find UBI useful? It is really frustrating to hear people argue that UBI solves problems that it does not actually solve.
UBI has no answer to automation. For one thing our current welfare state can already provide the basic necessities (for example, nobody ever starves in developed economies), and we can keep adapting it as things change. What we don't know is how we can have a functioning society where the majority of the population doesn't need to do anything.
UBI also has no answer for third world countries which have no capital to drain on a social spending. How is UBI going to work with failed states like Congo? Or Somalia? Or a developing nation like Bangledash? How is immigration going to work? Right now there is an economic case that developed nations can make for new immigrants, but in a fully automated world immigration is ONLY charity since every immigrant you take in will be a drain on your social system and provide no contributions back.
UBI is also ill-defined. Libertarians think UBI will replace our social welfare state (including healthcare system). Progressives, Leftists and Socialists will NEVER EVER agree to that. At best, they may see it as a complement to the existing welfare state.
So what problems is UBI actually solving for us?
