Earlier quoted context omitted.
If UBI is just a redistribution scheme and aggregate income stays the same, how is UBI than different from the various 'social' countries in Europe such as e.g. Sweden and Finland? Those countries have progressive income taxes and social benefits for those without work. Isn't this the same as what UBI would look like if aggregate income would stay the same?
UBI removes high marginal tax rate from poor households. See my other comment https://news.ycombinator.com/edit?id=23140692
In your other post you state that Finnish effective marginal tax rate for poor persons is more than 80%. Do you have a source for that?
