As long as those thousands have money or a need for your good's it will be ok but if banks start to foreclose and you are trying to sell on a tanking market it will all implode.
capitalism isn't bad
debt isn't bad
these are just ideas, system and instruments.
it is the individual that use them that is the problem...
human greed, excess is the problem not the instruments
and there are countless example of this written into history books
and there will many more in the future.
