I was fortunate to be among the people in the first group in this study.

The workplace I entered was entirely different from the one my children entered and the one my grandsons will enter is on another planet.

Reagan usually gets the blame for the reversal in the fortunes of the US worker, but I saw it starting under Jimmy Carter, who spearheaded the deregulation of the trucking and airline industries.
Because of deregulation, millions of high paying union jobs were replaced by low paying non-union jobs and once-powerful unions were rendered powerless.
In retrospect, Carter was probably right to deregulate trucking.
The current system is much more efficient.
I'm not so sure about the airlines. No one gave any thought to what the resultant low fares would do to already overcrowded airports.

Efficient or not, however, in the case of both industries, no one gave any thought to the social consequences, as this study shows.

Bernie gets that.
