I'm nostalgic for dose days as I believe the late 40's, 50's and 60's were this countries golden age.
Because the industrial capacity of the rest of the world's factories had been bombed to oblivion and we where the only nation who could still produce anything.
At the end of WWII we owned 80% of the worlds industrial capacity. Yes, that was a gold age for us, but not because we were so great, but because everyone else was suffering from the most tragic war in the history of the world.
