Eisenhower was a regular Nostradamus.
No doubt he foresaw the military-industrial complex.
But what about the health care-support industries complex? Or the financial services complex? Or the police-prison industrial complex?
There is plenty of money to be made from attaching your prospects to government, and lobbying the heck for things. The "war on drugs" builds prison populations, which benefit prison builders, operators, union employees, etc.
Government paid medical benefits doctors, nurses, other workers, plus equipment, suppliers, not to overlook Big Pharma.
Take a look at those involved with government bonds. Govt. employees themselves, lawyers, accountants, security firms, brokers, mutual funds, etc. Lot of high paying jobs involved, plus some huge commissions and fees.
