"Bringing down Apple may benefit nobody, but there is no longer any reason for Americans to care about the success of American businesses since they don’t share in the prosperity."

Precisely. Many Fortune 100 US companies took the vast majority of their tax windfall/oversea cash and bought back the stock. Before you say most Americans own 401K's and have benefited from this - the relative increase in 401K's is dwarfed by the increase in housing prices and general inflation. Most Americans have experience single digit wage growth since the early 1980s, while the cost of pretty much everything has increased by double digits.

Most Americans are worse off today (from an earnings standpoint once you normalize it for inflation and purchasing power) than they were 30 years ago.
