Yes, I think this is a huge problem -- if interest rates rise again, a lot of people will suffer. Therefore policy makers have a big incentive to keep interest rates low.
I don't know how this will end, but I don't think that the current low interest situation, which incentivises credit and discourages saving, can be stable in the long run.
Both of those things encourage economic growth, though. Until we come up with some better way of meeting our demand-side needs, rates are going to stay low.
