Hi there! How are you doing? I'm from Ukraine and I can answer all of your questions. The thing is that most of the people do not realize the seriousness of this issue. I understand it like no other because in my country there is a war just now. When you fase the problem you must make a serous decision. Most of the people decide to move with their families to get better opportunities and living conditions.
Those who have a big dream, faith and passion and BROAD VISION they move to another Countries or megapolisies. Those who want to live a regular life on a middle level - move to cities.
The unemployment is when the number of unemployed exceeds the number of employers. In fact in my country we have enough of working places BUT the month payment is 40$ while utility bills are 100$ per month. In 99% of cases Governments cause unemployment.
