There is enough greed to go around from CEOs, whose pay and perks know no limits and are unrelated to performance (seems the most creative idea they've had in the last decade is shipping jobs to low wage, third world countries) to seeking and getting outright government subsidies and tax exemptions.
Its too bad that corporate behavior doesn't provide much evidence that left to self regulate they will operate with much integrity. Regulations generally come AFTER some egregious misbehavior is discovered.
Getting something for nothing seems to be an American value shared by those at the top with those all the way down to the bottom. We don't admire integrity, fair play, hard work, and honesty, we revere wealth and wealth becomes its own morality.
Or, you get a group of greedy lawyers and politicians who go after your profits based on junk science like many tobacco industries
Junk science? You're kidding, right?
