We have not “allowed” corporations to get big - they always will, that’s the inevitable outcome of capitalism.

Yup, and it’s inevitable that weeds will grow in one’s garden and it’s inevitable that the viscosity of oil will break down in an engine and it will seize up.

Many things require maintenance. Capitalism is not different. Gotta do some trust busting now and then. Add some regulations on some industries in places where it makes sense.

Capitalism is a machine, and like any machine you have to do maintenance so it works well. Just gotta change the oil sometimes, no big deal.
