What do you mean by this statement? Everything that I have read on SS would contradict this statement. If you happen to maximize your FICA tax for 35 years of your work history then you maximize your SS benefits, as long as you draw on it after you reach full retirement age. Those who cannot maximize their FICA earnings will draw way less than those who have over a 35 year work history.
I didn't realize this until my dad pointed it out to me about those who earn more than the maximum, which is the following example:
If person A earns $50,000 a year they will pay the full 6.2% FICA tax on their income.
If person B earns $250,000 a year they will pay an overall reduced rate of the 6.2% since no more taxes are withdrawn after the cap which is $132,800 this year (something close to that number anyway) .
The other side of this is that higher earners more than likely save or invest some of their income and will be able to offset their future retirement payments from SS with investment dividends or some type of annuity.
I don't see how the higher earners get less than those who make less from SS. I see the opposite. Not only do they make more from SS but they more than likely have extra from other sources on top of SS while the rest get less from SS and probably won't have other sources of income at retirement.
