These are the ones that service everybody. Transportation, water, power, a few others...
Profiting from that for selfish reasons doesn't hunt well and does not serve the public.
Private corporations utilize those services all the time.
I got no problems with private corporations. Only when they invade my private economy. Too many bells & whistles accompany their policies. Leaving a one sided contract giving them full control over the details. Allowing them to change policy anytime they feel like it. Legally breaking contracts, so to speak...
I suppose my definition of contract means fair use and live and let live. I guess I've been hood-winked. Oh well, it's not the first time and it certainly won't be the last.
Live and learn.
Besides, all the public infrastruction within needs to be upgraded to achieve magnificence.
