Here’s a good example of “Distributed Costs and Concentrated Benefits”. Consider the taxi medallion licensing cartel in NYC.
There are a fixed number of taxi medallion licenses. They can be bought and sold. Recently, one traded for approximately $1M. There are approximately 13,000 medallion licenses.
The taxi medallion license holders own a State-backed monopoly/oligopoly worth approximately $13B.
The supply of taxi licenses is restricted. The net effect is that you can only get a taxi at the airport or in busy parts of Manhattan.
Occasionally, there is a proposal to increase the number of medallion licenses. The taxi medallion license holders, with a $13B State-backed cartel, can afford to spend a few million dollars lobbying against changing the law.
As an indvidiual, it doesn’t pay for me to spend money lobbying FOR more medallion licenses. Instead, I pay a couple of dollars more whenever I need a taxi, or I use another form of transportation.
There are are small handful of people who benefit from the taxi licensing cartel, the current medallion owners. Everyone else pays higher prices when they take a taxi, or a taxi is not available at all.
The medallion owners collect economic rent. Everyone else suffers.
The NYPD occasionally arrests someone for operating a taxi without a license. Due to lobbying by the medallion owners, a handful of police are dedicated to enforcing the cartel.
If the taxi medallion owners had to maintain their own private army of armed thugs to enforce their cartel, then it wouldn’t be profitable. Instead, this cost is externalized to the State.
This sort of thing occurs in EVERY industry. If you add them all up, it’s a huge increased cost and wasted resources.
