Hello dear @mintymile.

Very extensive post.

Too much population concentrated in a few spaces will always be a problem.
It would take a government with a lot of will to change and love for its inhabitants. Visionary and with great experience in the economic field, there is no place for mistakes or hesitations.

Great nations like China and the United States currently have seemingly strong economies. But the fact is that a hundred years have passed to reach this level. These nations have experienced stages of economic depression. The birth of industrialization.

Today there is more technology, but for the nations that did not take advantage of the last century, now the road to economic independence and development looks very rough.

Your friend, Juan.
