Fed is in complete control of every crash and every boom. They have put enough systems in place for a long time to be able to manipulate every aspect of the economy according to their wishes.

Here is an interesting rabbit hole: Alan Greenspan.

Apparently, Greenspan is the world's first computer programmer, who used the ENIAC in early 40s/50s and CIA technology that didnt hit the general public for another 30 years, to program manipulation of the economy.

This is quit a fascinating topic, and searching for "road to roota" will bring up some interesting tidbits.
