Agrarian and industrial both required many people to complete the jobs at hand. While technology requires highly educated people, it requires less people overall. How many offices have you been in where groups of employees perform useless or redundant tasks? I’m most certainly not on Obama’s or any union’s side, I’m just stating what I think will happen. If too many are on the dole or unemployed, our economy will stink. People will vote for free shit. Cheap Chinese crap isn’t worth the long term result. “Free trade” isn’t free. The USA’s quality of life will decline. Do you disagree?
The impact of economic isolation in a global economy is seen in two real world examples:
1. North Korea
2. The “Great” Depression in the US - note that elsewhere it was only called a depression. FDR tried to “protect” American jobs. How did that work out?
