This sounds like the Y2K doomsday scenario that never materialized. I agree that the politicians from the left have created a dependent class: they give them welfare, medicaid in exchange for their votes. But there other politicians who try to get the votes from people who have made it on their own. First all, who are these nations who have loaned money to the US? China comes to mind. But if you look at China, they have a surplus because they give little or nothing to the people. The great majority of chinese people live in the country side and they are very poor. They keep their manufacturing costs very low by paying workers poverty wages and letting all the pollution go out in the air. They plan on stopping all the factories and cars so that so that they can hold the olympics. That says how much China cares about the welfare of its people and the environment. The US tries to feed and take care of all its people, has done a good job in cutting back on pollution which costs money. So, you are saying that China who is letting its people starve or live in poverty or oppress them like in Tibet, all of the sudden is going to ask for its money back from the US so that it can feed its people when China doesn't care at all about its people now? Or maybe it is more like business or rich people that have loaned money to the US by buying its treasury bonds and not other countries? If the debtor nations can't pay back their debts, its going to be the lenders who will be left holding the bag like what were saying with the banks who are sitting on the subprime mortgages.
