My thinking is personal. I had the benefit of elderly members of my family outliving their contribution to SS. My dad lived to 95 but, of course continued to get his SS check until he died. He was a high wage earner and regretted the cap as well. I worked and contributed for 43 years so others could receive their benefit. That is how it works. I was totally ok contributing and would have preferred no cap on my earnings. It was a paltry amount given the tremendous benefit others got.
