Henry Ford wrote extensively about how to increase GDP. What is GDP? Gross Domestic Product in his opinion is chiefly driven by increasing the amount of developed power available. This is electrical power and transportation power from all sources… Dams, coal, solar, wind, and nuclear power.
Henry Ford wrote that developed power is the reason Americans of his time lived such good lives compared to the rest of the world… In Morocco, people had to thresh wheat by hand where in America that a machine that could thresh 1,000 times more wheat per hour than a man could by hand.
The way to increase the wealth of a nation is to greatly increase the power generation. Build more nuclear plants and hydroelectric dams, and more gas and diesel automobiles. Fight hard against those who try to torture government regulations into shutting businesses down that provide these services.
