in which he warned the nation about what he called the Military Industrial Complex.

It sounds scary like something out of a conspiracy theory or Sci-fi movie.

But what exactly what President Eisenhower afraid of.

What is the Military Industrial Complex?

It refers to the close relationship between military leaders,

government legislatures, bureaucrats and

private contractors, all of whom have a stake in our national defense.

Under our current system,

the US government has a monopoly on defense on the national level,

meaning that they are the only provider of defense to US citizens.

You can't start a private army to compete with it.

But that doesn't mean private companies aren't involved.

The government purchases military equipment and

services from private firms, including uniforms, vehicles, weapons and more.

In order to secure defense contracts from the US government,

these companies must navigate a massive administrative bureaucracy.

Because this is difficult, most private firms can't successfully compete for

these contracts.

Instead, a small number of companies who have close relationships with government

officials and specialize knowledge of the process tend to win most of the contracts

and these contracts are quite lucrative.

The US defense budget is massive, by far the biggest in the world.

In 2015, the US budgeted almost 6 hundred billion dollars for defense.

And defense contractors that provide the government with military equipment and

services naturally want to secure as much of this budget as possible.

They do this by spending significant amounts of money

to gain access to politicians and bureaucrats.

And to influence their decisions.

The strong ties defense contractors develop with politicians and

bureaucrats lead to what is known as the revolving door

where people hop from jobs a private firms to jobs in government and vice versa.

This dynamic only tightens the relationship that private

firms have with government.

And allows them to take advantage of these connections.

This messy entanglement has two important implications.

First, crucial decisions about war are not necessarily made by dispassionate

politicians comparing the costs and benefits of military action.

Both government and private business are active participants in the defense sector.

And each attempts to influence and shape the behaviors of the other.

When you are manufacturing and profiting from military equipment.

You stand to benefit greatly from an interventionist firm policy.

If you persuade policy makers many of whom are your friends and

former colleagues to pursue military action.

It's more business for you this can result in wars

with people shipped off to fight and die without making the nation any safer.

Second, the government's defense budget is fought over

by the many firms looking to secure military contracts.

If I'm a manufacturer of tanks, it's in my best interest to try to get

the government to spend as much of its defense dollars as possible on tanks.

Even if this is obviously a poor defense strategy.

Private defense seek to grab as much of the military budget as quickly as

possible, with little regard for the broader, external costs of their behavior.

Yet their lobbying efforts still shape the decisions made by government officials.

Together, these effects of the military industrial complex shape

the incentives facing both private and government actors in the defense industry.

This means that rather than only considering the public interest,

military decisions are influenced by special interest in the private sector,

which can have disastrous consequences.
