To prevent tragic ethnic conflict. I thought why not empower countries with or without a minority for a win-win peaceful future.
A simple part of that would be to build. To enhance housing for people. If being homeless means you cant get a job, education etc then a better or enhanced house could perhaps be closer to a better job. More money for country.
Then you have millions of smart assets in the form of houses people own. This will enable loans to buy cars and other things. This would jump start the economy and bring a peaceful global future.
