There are too many people on this planet. We don't need nor can we support any more people irrespective of creed, color, race, sex, orientation, etc.
There fixed that.
That's where everything starts. And, yes, no nation can fix all the shortcomings of that and other countries and cultures.
Not everybody is smart . Not everybody will be able to get a job in their country. Not everybody is born healthy. Not everybody gets or can get a good eduction. Not everybody is ground in reality with wishes or life stye. Not everybody lives within their means..........
This list is endless.
This will sound very cynical and almost "trumpesque", but nature tries to regulate itself by throwing out diseases we haven't figured out to cure yet and actually wars, natural catastrophies and other disasters help keeping population somewhat in check.
Humans are not capable of self regulation.
We only get upset about the results.
Back to Trump. He will stick a needle into every established pile of political dirt and may cause a few changes.
As misguided and not well thought out as it seems a lot of it is just to highlight what other presidents and politicians never tackled.
Laws, politics and complacency will swing everything back to a new normal when he is done.
The world is directed by money, any change has to be "profitable" for at least one side or it's not happening.
