I'd argue we could get a long way by removing legal protections and incentives for such large organizations. Those protections and incentives seem to me to be the root cause behind such large centralizations of power.

If companies and their leadership couldn't operate so unchecked by our existing laws and public opinion we may not have executives worth worrying about.

For example, if taxes were so easy to dodge and if the public actually had a chance to sue large corporations for damages they may not get so large. If, when losing a lawsuit, companies couldn't shuffle around funds and spin off dummy companies to dodge the pain, and if they weren't often forced to pay pennies on the dollar for lost suits, they may think twice about doing some things. When you know your entire business is actually on the line you have to be more careful.

Throw in election and lobbying reform and we could at least be having a much different conversation about corporate power.
