I mean, as Americans would consider it (and not the red scare "socialism" of Fox-types), what is often the colloquial military industrial complex is already socialism, without incoming the privatized profits and socialized losses enabled by regulatory capture or too-big-to-fail. It's a single-payer operation (with strict caveats) where the government not only pays and sets prices through cost-plus schemes (that may or may not separately be perverted and exploited) but they also control the products produced. Even universal, single-payer healthcare as a practical concept is likely less socialist.

In case you're wondering, this is an argument for universal Healthcare and not for the US government having to buy aircraft carriers off the rack or against it limiting/ controlling whom besides itself can pick up reaper drones and hellfire missiles.
