~90% growth in spending over a decade is pretty significant.

Also, don't conflate the federal defense budget with the MIC.

I would think that no one has a problem that our military has been getting bigger because we simply have more resources/capital/(whatever the proper term is) to go around.
A very strange thing to say.

The MIC itself, as an interest group, is not in a category separate from agribusiness or Big Oil or the AARP, in terms of influence. The military-loving demographics are much stronger in that. I took issue with your claim that the MIC has shrunk, and that military spending has no potential for "runaway" growth.
