I hope you make the same contention about accounting, lawyering, and medical practicing, as well.
I would also expect to hear no complaints about free-trade, outsourcing and evil Walmart.
I will acknowledge that the federal Congress has the enumerated power to "regulate commerce," commerce being defined as trade or exchange, and relunctantly agriculture, manufacturing, or mining for argument purposes.
Congress cannot use this enumerated power and violate the Bill of Rights.
Anti-trust laws appear to violate both Amendment V and Amendment IX.
