The central organizing principle of US society is individual freedom, which causes the crime rate to be high, so you need a high proportion of guards (sensu lato) to combat that.
In countries where the clan is the organizing principle, in contrast, your family members act as a check on your behavior, but those family members do not count as guards. (If you live in the US, your family has less influence on you because you need them less.)
There is a low level of guard labor that needs to happen in a free society, that's true, but it shouldn't be _increasing_ as a percentage, and it's not a good sign for the health of society at large if it is.
Cooperation _isn't_ the natural state of people, and we need to make sure we're increasing the benefits of working together and not just the punishments for crime. Right now, the benefits of the economy are accruing disproportionately to the wealthiest and we need to do something about that, because we're destroying the motivation for people at the bottom rungs to "play nice".
