Evolution of economy

It's bad that I don't remember whose ideas these are, but basicly...

Recession is bad. Many people and business suffer. Etc.

But this is not only a bad thing since recession purifies the economic landscape. It exists to destroy business ideas which do not work or are not really needed.

Recession should be seen as an opportunity to put more shots on renewables, economic sustainability and efficiency. It should also be a point where the laws of the economy are readjusted so that there will be no recession for the same reasons again.

Humanity develops through dialectic - trial and error. Then again, it is a different question whether this is now going on or not.
