That's sort of fundamental to how markets work. If you're not willing to do this, the government should not be willing to grant you license to operate.

Yea, don't worry about morality if it gets in the way of money. Laws don't apply if you have enough cash. The long term outcomes of allowing this to continue, I'm sure, will be great for everyone involved.

you are right, there should be prison punishments for the managerial class, otherwise its just an added cost of business

"Bob, we need you to take the fall for us and go to prison for 10 years. We'll look after your family meanwhile, and pay you handsomely for your time."

Plenty of other organisations (of various sorts) are ok with that. Theres no reason Google and similar wouldn't figure out something along the same lines.

Under the Sherman Act, the criminal penalty for conspiracy to monopolize is up to 10 years in prison or $10M for individuals, and up to $100M for a business, OR up to twice the monetary benefits to conspirators OR up to twice the money lost by victims, if those amounts are over $100M.
