One of the big lies of capitalism is that competition is desirable.

Competition is desirable for the consumer, not for the producer.

In addition to this, I would add that competition can take many different forms. I think it's very useful when it inspires everyone to do better and everyone can shake hands afterwards because they enjoyed the journey. It's less than useless when people use it as an excuse to cut each other down without improving anyone's performance, which is disappointingly often.

If you meant crony capitalism, sure. Then you'll use enough old boy tactics to ban your competition or give you a state-enforced monopoly or deal (effectively skewing the market in your favor and against your competition).
