As I stated, I'm not in favor of giving tax money to corporate executives. However, the salary cap issue is already sending shock waves through Wall Street. America has seen this before, when federal highway dollars were an axe held over states to coerce them to set the 55 mph speed limit, enact seatbelt laws, drinking ages, etc.
It's also a lot like the IMF making loans contingent on the subject nation enacting certain economic policies.
Wall Street doesn't like it because it sends a HUGE signal that this administration tilts toward socialism and views capitalism as evil. Every time this administration sends that signal, the Dow drops.
Like it or not, Wall Street drives our economy far more than Pennsylvania Avenue. Private industry, not government, provides jobs, income, and builds wealth. We need to keep our heads about us and avoid the temptation to put the screws to the engine that actually builds our economy in favor of pet social programs that drain it.
