I personally feel that most of the working citizens in America, today only work so they get payed and they have something to look forward to after they have retired from working their whole adult lives. It's nice to be treated every once in a while when you've done something great. It's even a possibility that a good hand full of people might even quit working just because they don't have something to look forward to. Maybe if they got payed more and put it away for a rainy day they might not complain, but there is always a chance.
Causes of war could include economic, political, colonial (fighting against colonial power), conflict over territory, conflict over resources, colonial expansion, or an attempt to build an empire. The war in Ukraine is a result of the desire for territorial expansion by Russia, preventing Western intervention in the Ukraine, destabilizing Ukraine, and also to show that Russia is willing to fight to prevent its satellite states from joining NATO.
