What did harding, coolidge, and hoover have in common, regarding their economic and political philosophies

All 3 believed in a laissez-faire economic policy.
This means that the government does not interfere in the national economy as a whole (rather than just businesses) in any MAJOR way - rather than not at all - unless absolutely necessary,and then only to give it a nudge back in the right direction. :) hope this helped!!!

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature
