Universal Basic Income (UBI) means that each person is paid (by the government) enough money that they can afford food, shelter and even a carefully budgeted social life without the need for work. The extremely poor would be paid exactly the same weekly wage as the extremely rich. Where would this money come from? A tax on the obscenely rich of course.
Figures from the World Inequality Report show that while the income of the US population grew by a total of 63% between 1980 and 2016, the income of the top 0.001% in the US over the same period grew by a gargantuan 629%. When we look at the global rankings, we see that, for the most part, the most equal countries are also the happiest and the least equal are the least happy.
