There are several things that can be done to prevent the problem from occurring again. Congress has done nothing to address the root causes. They threw 800 billion at the problem and it has had little to no effect outside of the banking industry because the problem isn't money, the problem is the system and until this is addressed effectively with legislation we will continue to have an unstable economy. If people are fine with having the economy come closer and closer to a repeat of 1929 every 5 years until eventually we have something that makes 1929 look like a 'jobless recovery' then by all means continue as before. If you do what you have always done you will get what you have always gotten. Insanity is doing the same thing and expecting different results.
Assuming you were being serious (not always a safe assumption, I know), the point of the thread seemed to be that the apparent focus of the executive and legislative branches on health care reform is to the detriment of the recovering economy. Everything I've read and seen indicates that the economy is recovering just fine (not great, but fine) and there isn't a whole lot that can be done legislatively to speed up the process. So I don't understand your point.
