I mean, this is a hard question to give a blanket answer to, since literally every industry has its own peculiar features and will therefore require a unique relationship to the government, but in general, I would be in favor of much stricter limits on corporate consumption, particularly as it relates to the environment, stronger restrictions on the ability of management to delimit the right of workers to organize collectively, a removal of the primacy of shareholder returns as the driving force of corporate action, a revocation of corporate personhood and the diffusion of responsibility for white collar crimes both domestic and abroad, requirements that companies must interface with the government regularly in order to uncover potential problems before they become a systemic risk, rewards for whistleblowers who expose cooked books and collusion, and a general willingness on the part of the government to break up companies, like Wal-Mart, that tie too much of the economy into their regular business operations.
Note that I don't actually think any of this will happen.
