In 1968, in a summer job, I earned $200/week as a kid electronic tech, fixing car radios - with 10 weeks pay I could buy a brand new VW (advertised at $1895). I don't think I could buy a new VW with 10 weeks pay today, as a college grad with 30 years engineering experience. I think that the average worker has had their real earnings greatly eroded over the past 25-30 years. The ruling elite have not seen such an erosion in income. The worker class has. It is high time to push back and get an equitable share of the wealth we produce.
Not every net growth is good. For example the system in which one family lives on 70K a year while the other lives on 30K a year is better than the one where one family lives on 100K a year while the other lives on 10K a year.
Also the larger size of economy is not always better - the day you merge USA with Latin America you will get significant instant "increase".
