You really don't think the fundamental IT technologies used by every US industrial company didn't add any wealth to our country?
Is natural resources your only measure of wealth?
You know I’m not being that simplistic.
An extreme example: You find a million dollars worth of gold and you increase wealth by a million dollars;
You make a million dollars making/selling emojis and you don’t increase wealth at all.
IT has done a lot (are there FINALLY any ‘paperless offices?) to increase efficiency, which creates new wealth, but mostly it hasn’t increased wealth.
