That is why I specifically said the FICA "income cap has been raised every year". It is a higher tax payment every year -- no two ways about that.
The person making $200K is paying much more in FICA. And if cap limits are significantly raised or eliminated...the payment will be MUCH more. And no, you are incorrect ...the "probability is higher on the person making 50K" to not get back what they paid. You may not be aware of this...but there is a monthly cap on the amount of SS benefits. It is currently less than $5K. There is no way a higher income individual gets a return with SS. (note: I am not against that. I want SS to continue and I want politicians to bolster it. But further increasing tax burdens on tax payers should not be only solution.
I want funds for SS. I've paid into the system for years. I've known for a long-time it is not a good return on my personal investment, but I understand and want SS to help be a lifeline for our seniors and disabled to live. That said, some of the proposals to eliminate, or drastically increase, income caps are not fair, IMO.
Yes, discussing raising the retirement age should be on the table. When SS was first brought into law, the average lifespan of a male was 61 and a female was 65. It is now 75 and 80. Raising the age a small amount combined with a slight adjustment with FICA caps is the best start, IMO.
And yes, I agree it is much more nuanced than what can be communicated in a half-duplex manner of a message board.
