Once a business becomes established and enjoys a measure of success, a narrow view of its own interests can lead its principals to thwart innovation by others, and this is usually done by influencing the way laws are enacted or enforced. At the local level, this kind of rigging of the system is often done through zoning restrictions and other regulatory measures by city and county governments. – Acton Institute
A guy I worked for in advertising years ago tried to freeze out the local free-lancers by organizing a group of established agencies to petition for licensing. As I recall, the effort fizzled, but not because any of these boobs realized how selfish and self-destructive it was. After all, the small clients cultivated by free-lancers often went on to become big clients, at which point they transferred their business to the agencies.
