Unfortunately money plays a big role. The US is different, with good paying jobs for engineers being common but believe it or not, that is not the norm everywhere in the world. Sometimes people need to follow the money. I think this plays a big role on the russian side of the war. Their economy isn't very diversified and the state owns the means to a large portion of the economy's production. If you need cash, a good way to get it is to do putin's bidding.
