Can't recommend the first three podcast episodes enough. MMT theory.
Government creates money, taxes destroy money. The idea that the government needs taxes to run seems on the surface to make sense, but if you think way back to the beginning, it would have been impossible for a government to originally tax first and spend money second. They had to have created money first, spent it, then taxed it last. That order means taxes are not necessary for the government to run. The only constraint is inflation, if the government spends too much and employment is completely full then goods and services hyper inflate. So their job is to create full employment without spending anything beyond that and creating hyper inflation, which means only at that point do they need to tax. Or they can tax things that are seen as a negative to society, tobacco, alcohol, excessive inheritance, carbon consumption etc.
