Then the good professor argues for a return to these good old times. The historical reality begs to differ. Far from being "virtually nothing", the US manufacturing output was the first in the world as early as 1890:
This economic growth was, by the way, happening behind some pretty heavy protectionist measures (initiated by none other than Lincoln):
But maybe this economics professor wasn't referring to economic output? Let's look at the principles that guided Franklin Delano Roosevelt, under whose leadership the US became acknowledged as a military superpower as well:
"Throughout the nation men and women, forgotten in the political philosophy of the Government, look to us here for guidance and for more equitable opportunity to share in the distribution of national wealth"
A complete opposite from the article's description of an ideology where "no one could count on government assistance"!
In conclusion, the article's premises are based on a very shaky foundation and expose a shocking ignorance (for an economics professor, at least) of US history. And if the foundation is bad, I don't think the rest of the edifice hold up very well either.
Thus the author is in no way to blame, but those in this community who up voted it.
