Ever heard of Enron? Also just google for "nuclear corruption" and you'll get a lot of reading material. For example this article http://nautilus.org/napsnet/napsnet-policy-forum/nuclear-cor... which has links out to sources including the US DOJ about corruption cases in Korea, Taiwan, Japan, the US, and more. It's a huge problem. And the key players would like to keep it all hidden, so your being in the dark about it is no surprise.

Corporate overlords (can't tell if you are trolling, but I'll answer) is just a shorthand for corporate decision makers who prioritize corporate profits over other considerations like consumer benefit, care of the environment, freedom of consumer choice, fair dealing, etc.
