"From each according to his ability, to each according to his needs".
Aka. "redistributing" wealth. If your insurance program were an optional program, I'd be ok with it. But the act of FORCING me to participate turns it into a redistribution program. I will have been forced against my will to pay ten times what I'll get back out of it.
It’s not a redistribution scheme. It boils down to public purpose. The majority of Americans will need SS, that’s the reality of the situation.
SS benefit payments are done through keystrokes. The whole point being able to move resources to grandpa, so we credit his bank account so he can purchase groceries rather than dumpster dive like good old days before SS.
Why do we have a payroll tax? It’s actually not to fund benefits, but rather to discourage workers to purchasing all the available output, which is would compete with grandpa’s small SS checks he uses to buy the minimal amount of real goods and services. If we exhausted capacity, then we would have inflation.
The only thing that should concern us would be real resources. The idea is about having sufficient capacity to satisfy grandpa, grandma, average workers, disabled people, and their family members who receive Social Security. We don’t have a problem with real resources today, and we haven’t had a problem since the WWII era when half of production went to the war effort.
The US has operated way under capacity. In point of fact, our economy would perform much better if we paid all of our grandpas more SS benefits. This would increase aggregate demand, increase employment, and give businesses a chance to sell more stuff, so then can increase profits which translated into increased investment and capacity.
If people like Paul Ryan and nuts like Ron Paul get their way, each generation of workers will to increasing set aside more savings. This is so they can avoid eating dog food or reduced to dumpster diving or living with their children who probably rent that fact the mom and dad are living with them. Basically, consumption from wages will not be sufficient for firm to recover their costs. It creates a vicious cycle. Savings would be lower since enticement to innovate and invest would be much lower, etc. Attempting to save more doesn’t mean you’ll save more; we call this Paradox of Thrift. We’d have to have trade surpluses or budget deficits increase to make up for the gap of decreased investment. We then end up with much less savings with having to support seniors and others kicked out of the SS safety net.
Historically, we know that workers really never acquire enough savings. Take a look at the 193s before SS. It was ******* deplorable. Surveys tell us the elderly had no means of support and were relegated to fighting with stray animals for food and living in poor houses.
Thanks….but no thanks.

This why Americans contribute to SS. Or we can go back to the glorious days of the 19th century and early 20th century.
Edit to add:
Personally, I’ve always been vehemently opposed to the payroll tax, since it's a shitty way to ensure that overall demand doesn’t outstrip our ability to produce. We’re better off with a progressive tax for everyone. Payroll taxes decrease the incentive to work so to speak. This is the exact opposite of what's needed if the problem is decreased production.
