Why has the power to regulate interstate commerce become such an important power of congress?

[Illuminati]

another word for interstate commerce is free trade. When corporations can freely trade with other countries, it increases productivity by giving a greater choice of products. When governments regulate they can choose which countries are okay to buy from and which are off limits, thus restricting the free markets throughout the world. Governments notoriously pick and choose based on political motivation and not economical competence or social equality.

So, as an evil illuminati bent on world domination, it is my duty to make sure the government restricts as much as possible, not allowing you to buy from Cuba and allowing their economy to grow or to buy from Iran-we hate those guys. But, by all means, buy from communist china so that our evil empire can grow, grow, grow!
