SO GET RID OF THE MANPOWER:

Whenever anyone brings up the rising military power of China, Russia and other U.S. rivals, some pundit usually pops up to remind us that America is still overwhelmingly dominant both in terms of military capability and spending. The pundit will generally offer you a chart like this one, which shows American military spending dwarfing everyone else's. The message, of course, is that the U.S. outspends all its rivals, ensuring its continued military dominance.

But there are several problems with this perennial talking point. The first is that these dollar numbers aren't adjusted for the cost of anything that any of these militaries buy. The lowest-paid U.S. soldiers earn about $18,000 a year. In comparison, in 2009, an equivalent Chinese soldier was paid about a ninth as much. In other words, in 2009, you could hire about nine Chinese soldiers for the cost of one U.S. soldier.

Even that figure doesn't account for health care and veterans' benefits. These are much higher in the U.S. than in China, though precise figures are hard to obtain. This is due to higher U.S. prices for health care, to higher prices in general, and because the U.S. is more generous than China in terms of what it pays its soldiers. Salaries and benefits, combined, account for a significant percentage of military expenditure.
