It depends on the invading nation but the difference between the two has to be substantial to be worth risking your life. If lets say my quality of life would become much worse (like cutting my electricity, internet, food etc) or the invading state had plans to kill me and my family 100% then I would probably accept joining the army but that's because I hate emigrating elsewhere to avoid it, I'm not the type who will move during a crisis, I didn't and never thought about it when my country faced a terrible financial crisis. I would still wait a lot though before conscripting.
