Evidence of Declension--US Going to the Dogs

Don't know why but today I want to write about what can be seen as evidence of decline in the U.S. over my lifetime:

• holidays have changed.  When I was young blue laws meant many stores were closed on many holidays (except George Washington's birthday) and holidays were celebrated with more attention to their significance.  The rise of shopping every day of the week and every evening has enabled women to participate in the market economy, getting money for their work.
• the culture has gotten "coarser".  Expletives abound, porn is available, available not only for "normal" sex but all sorts of "deviations".  There's a possible relationship to the greater openness about many subjects ("cancer" was discussed in whispers when I was young).
• the economy seems to have gotten more concentrated--we've lost a lot of chains of department stores, a lot of family farms, a lot of local stores, a lot of newspapers. On the other hand, we used to have just 3 TV networks, and there were concentrations in steel, autos, and coal--the sectors which used to be the pride of the country and the arena in which we competed with the Soviet Union.
