I'd like to propose a new word to fill a gap in our vocabulary:

Literally, faith in competition or rivalry.
The belief that all competition is inherently good and that since some competition is good, more is better.
The irrational belief that competition is the solution to all problems.

ORIGIN this post: from late Latin competitio- 'rivalry' + from Latin fides 'faith' + -ism

Competitiofideism is a widespread belief among American political philosophies and economic theories. I think that competitiofideism is a useful term for classifying these views.
