I accidentally dropped a few lines from the original post. When the state grants the corporation it is creating an artificial person who will live in perpetuity. This artificial person can enter into contracts, sue and be sued. At the same time the state granted corporation shields its owners from most personal responsibility for the actions of the corporation. The bigger and more powerful the government, the more useful it is to the big corporation.
Examples are literally endless.
The Interstate Commerce Commission was established in 1887 to regulate the railroads. The ICC fixed this terrible discrepancy by fixing the price per mile of the long haul routes at the much higher short haul per mile rate. Since the ICC fixed the price no railroad could charge less. It grew by leaps and bounds because trucks could easily undercut the artificially high, fixed price maintained by the ICC for the railroads. Trucking was a relatively low capital operation, therefore fairly easy for someone to start a trucking business and thus highly competitive.
