That's not accurate. SS returns don't scale directly with payments. The more money you make the less you get back from SS (percentage-wise). There are also some other rules regarding marriage. It's redistribution of wealth and is not simply money back in direct relation to what you pay. (I am not taking any ethical or political stance on wealth redistribution. I am just noting that the previous description of SS is not accurate.)
Note that I said "correlated with" and not "proportional to".
While technically true, I wouldn't really call it a redistribution of "wealth", when income is capped at ~110k for the SS calculation. Wealthy people are hardly affected.
