Agreed. However, as a military officer I think this a bad idea.

The US military is actually somewhat small considering the size of the population, so a mandatory draft wouldn’t apply widely enough for the mentioned benefits to materialize in a meaningful way for social change.

It would also change the internal social nature of the military by filling it with people who don’t want to be there. In addition to being a part time military officer I am also a senior developer at a really big bank. The disciplined young people in the military seem substantially less entitled than some junior developers I have worked with. In the military I can choose to raise performance standards for the people I manage, but in the civilian world if you try that people will bitch and go get a different job.
