1) the money that stays with rich individuals is generally 80% saved/invested, that investment does not have nearly the same level of economic stimulus that 50% of that 80% would if it was giving to the poor/middle class
2) we agree
1. we should spend effectively 60 new tanks that the army doesn't need a year is bad, when the coast guard gets a new ship and their reaction is guess we have to man a 9th cruiser, rather great now we can more effectively guard the coast is bad. trillions on a failed new air-plane that we keep funding is bad.
2.if you want to pay a private insurer more money than you would for public health care be my guest but the advantage to public health care is lower cost for medium to good healthcare for everyone. with the private system we have now unless you are paying primo dollars you are getting shafted by insurance companies either 1. over charging you or 2. are being sent to an underfunded understaffed too small public hospital regardless of how far away it is because the company gets better rates there rather than the private hospital down the street that is 50% occupied because the company would have to pay more. and I want to be clear if all hospitals were being used only by the populations they were meant to serve or being used equally this public hospital would not be underfunded or understaffed or too small.
3) the have privatized social security, if you can afford it great but ss is a plan to provide quality of life for individuals after they retire, if you privatized it many people would be without any form of retirement and would work until they die, or simply live in destitute poverty until they die because many people do not make enough money to save for retirement, short term they would rather spend that money that is taken out for ss on feeding their kids a little better or paying for Johnny's soccer team, they would never have the means to save so privatizing ss would lead to a net loss as a first world society, not only that ss is guaranteed, privatizing it is not and many people who invested in extra ss retirement saving rely on ss because their saving went away due to bad investments. Privatizing education costs more and comes directly out of the pocket of the the person poor people would not be able to provide an education for their children and would further exasperate the cycle of poverty we already have. their is no logical and realistic argument for private education, and the only argument for private healthcare is one in which the country has a powerful middle class and even then it is arguably better for a public healthcare system anyway.
