I am not sure if overpopulation is the main issue, rather it is resource distribution. The system is designed to put the resources in the hands of the few and keep it building there. It breaks eventually.

If you learn and train as a competent professional, the future is a peaceful prospect.

This is struggling now, since a lot of the trained professionals, are finding themselves replaced. This happens naturally, but the cycle is speeding up, so training isn't enough to earn for the 45 years it needs to earn before retirement.
