Statistically speaking, no we aren't. That ship sailed.
Exactly. Most people won't work hard unless they are forced into it. America has chosen communism right now because they are over fed, distracted and lazy to the core.
The original colonies were basically communist and failed because people at that time were lazy. A certain percentage of the population has always been lazy.
The only difference now is the lazy people control the policy. Change that and America will return.
