Note that the increasing cap is not just an increase in taxes on upper-middle earners, but is it a benefit cut for those earners who are below this line, and think themselves unaffected. They are decreasingly vested each time the cap rises.
In the 1960's my young engineer father told me that he stopped paying SS taxes about in April, and was then fully vested. Now, many or most young engineers are not even fully vested, even after paying 15% all year long. They won't get full benefits.
Want to bet??? I am a small buisness owner and there are few loop holes and NONE that i am aware of that will elliminate "most of these taxes" as you say....
