That's very true; also, to consider, is that once there are only a few big businesses in a single sector they get to [via lobbyists] have more access to their politician's ear, which means they can manipulate the regulations to further hurt their competition.
One thing I’ve noticed between the left and the right -
both recognize that big business is tangled up with big gov’t.
But, from the conservative point of view, the “problem” is the power of the gov’t being used to interfere with commerce,
and the left sees their beloved benevolent gov’t being influenced by big business.
The solution would be to have the gov’t NOT HAVE THE POWER to be able to benefit one business over another,
but the left would see that as a serious detriment to the ability of their beloved benevolent gov’t to “do good” on their behalf.
