Governments and other ruling organization have a long history of snuffing out certain companies of an industry before they get so big they can compete with the ruling organization (RO).
What the RO does is work out deals with some companies of the industry. Those that make deals with the RO get preferred treatment (monies, contract preferences, etc)...the others get oppressed. It has happened in the steel, railroad, apparrel material, fishing, military, agriculture industries...and recently the banking industry has fallen to this pseudo control of the government.
Why is MJ illegal? Cuz, a long time ago, the US RO determined made deals with cotton barons...and they both drove MJ underground.

Anyway, as stores pay "protection money" to the mafia, companies give the US RO monies and special deals.
Politicians love to say that the US is so great because it has never taken land in the wars that the US was victorious...well, that's because the US RO are worse that conquerors who took responsibility for the land they conquer. Again, as stores pay "protection money" to the mafia, these lands give the US RO monies and special deals...mostly special deals (e.g., labor, vacations, raw materials such as oil, etc.).
Obama is basically the world's Godfather.
THAT is just part of the big picture.
