The people who are working in STEM don’t need loan forgiveness like the a lot of other people who took loans to study in fields that don’t end up contributing to the military. As for healthcare I’m referring to things like trauma and human performance, if war breaks out this is critical infrastructure. I’d also argue that the cost of having a soldier tear a tendon and have to leave the military would be large and happen often so being able to rehabilitate and get them back to work is critical. Once a veteran is finished the government don’t care because they can’t contribute.

You have to remember the military industrial complex is a self sustaining machine now that it’s beyond reining in. It will keep policy in place to keep the cycle going. The economy now depends on it and needs wars or at least the ability to pressure countries into doing what they want so they can extract more money to feed it
