Except for military spending, that question is always asked.
Health care.... where will we get the money?
Education....how will we pay for it?
Roads, bridges, environmental clean-up....where will the money come from?
Well, fellow commodities, the money will come from where it always comes from: LABOR! Even in all-out war such as World War 2 there was enough labor for both guns and butter albeit some shortages in non military goods. Otherwise there is not only enough labor, there is an excess! The other part of the equation is materials. As yet, as of now, at this moment the planet has enough stuff to take care of now and to have enough for a few decades and maybe even a millennium or two, IF it is handled wisely. Here is where we get political: corporate capitalism is not able to handle it wisely. EXAMPLE: There are 3 million more people in the U.S. every year needing more goods and services. In spite of this ever-increasing demand we have economic CONTRACTIONS periodically. More people need more things yet the economy CONTRACTS. Go figure.
