Social Security is one of the greatest scams of all time.

Generally speaking, this is how it works

Lower Income families pay into it longer (didn't go to college, have to get a job and start getting taxed at 18 vs. going to college and started to be taxed at say 22)

Lower Income families receive benefits for less time (pretty much all statistics show that the wealthier you are, the longer you live)

Lower income families pay a higher percentage of their income than wealthier families. (Social Security only on the first ~$130K in income. It's a regressive tax)

Lower income families are paid out less in benefits. You get paid out based on what you pay in.

Wealthier families typically have other passive forms of income that are not subject to the Social Security tax, this means that if they get to keep this income stream going into retirement they are at a massive advantage over lower income families who if they have to work a job in retirement that again have to pay Social Security taxes on wages they earn.

In addition to all of this, upon death of both the primary and spouse, all the money taken vanishes and cannot be passed down to their children or beneficiaries which only compounds wealth inequality.

In short, Social Security is a regressive tax that unfairly penalizes the poor and provides a higher welfare pay out to families that are wealthier.
