Corporations don't care about equal opportunity, just the biggest bang for their buck, and they don't care how creating that revenue stream for themselves affects ordinary people. Government is the only counter balance to that reality. The weaker, or limited the government, the greater that imbalance tips away from the citizens in favor of the corporation.
Give corporations clear rules and certainty, they will invest more, and aggressively if they can make a longer range business plan, instead of short term reactions to changing government policies. Specifically congressional bickering every few months over that policy. We need a 10 year deal, not a 3 month one.
