So you're saying that people should do busywork now, just in case we need to go to the factories to support tomorrow's war? Forgetting the fact that the factories are already automated, and going to war won't un-automate them, war is ever less likely and smaller in scale as global prosperity increases.
Americans are more and more averse to going to war, which is why the USA is sending drones instead of people now. The situation is similar in Europe. Not so much in the other parts of the world, though.
A reasonable explanation could be proximity: When the war takes place in their own country, people are more likely to pick up guns instead of waiting for drones to be sent.
I'm guessing you're young? Seems like we were a lot closer to WW3 in the 1980s, and it's only been getting less likely since then. The US hasn't had a draft since 1973.
