Is being competitive bad?

Some religions and philosophies seem to look poorly at competition and at anything “competitive”, saying that it’s bad as pit people against each others. 

Yet, I’m one of these individuals who have grown into thinking that competition was good and was one of the pillars to growth and enrichment, both mentally and materially. 

Often, competition is equated to capitalism and its endless drive to grow and improve whatever is on its way in spite of all of its ill-effects, but by the same token, material and social progress are the results of various forms of competition and it makes it hard to condemn that drive altogether.

I'd think that, in the end, the healthier form of competition is the one we can hold against our own selves and I hang on to that one as a motivator for personal growth, healthy as well as good mental living! 

This is in fact what competition in sport should always be about, but too often, it gets hijacked by hubris and become yet another capital sin...
