What was it that you considered the American dream then? It was no myth. It was a reality for millions for decades. For the longest time it meant a promise of the possibility of prosperity and success. For a lot of people who came from nothing, migrants etc., expanded their opportunities on a massive scale. People moved, escaped, etc from their own country of birth to come here for opportunities that was never available in their own. Existing citizens who grew up from poor or meager beginnings later in life thrived and flourished as a result of such opportunities. As a young girl who migrated from France I experienced this first hand. My parents had nothing except the will to thrive in a country that gave then more opportunities they could never get in France. And it happen for them as well as a few other family members.
I understand what you are trying to say but it has nothing to do with the american dream. I can see it being hampered by the growth of government tho. Maybe that's what your saying?
