Hoover was an economic conservative, and did not believe in federal intervention in the natural cycles of the economy. It is worth noting that the thought the Depression would be much shorter than it turned out to be. He was also fearful of establishing a permanent situation in which the economy was dependent upon the government, especially with regard to welfare programs.
Hoover's fear was that the country would be permanently weaker if welfare programs were introduced, or if the federal government became overly involved in the banking system. Towards the end of his administration, as the Depression dragged on, Hoover conceded a bit on this point, and introduced some Federal lending programs to bail some financial institutions.

What you are describing is the system of checks and balances.
In the United States there is a system of checks and balances. In our federal government, we have three different branches including the executive, legislative, and judicial. In our system, the executive branch consists of the president while the legislative branch consists of the Senate and House of Representatives. These different branches all have the ability to check the other branches. This ensures that no one branch or individual will gain too much power.

This caused many somewhat wealthy people to build actual fallout shelters in their backyards, especially during the fifties and sixties. Other than people almost constantly worrying about the cold war going hot, I can't think of much more going on at least in the US
