Young people aren't going to be able to afford a child with a couple percent payroll tax cut. They need healthcare, time off of work, and a decent school to send their child to.
If we cut Social Security young people aren't gonna be able to have children because they're gonna have to spend more time and money taking care of their parents. Social safety nets make it easier for people to live a comfortable life.
Social Security would be completely solvent if we didn't make poor people pay to support other poor people, and instead tax rich people for it. It's built on a regressive tax, and the wealthy don't pay jack shit.
> Let's not make poor youngs (nearly all of them) pay for olds (rich or poor).
The problem is, this implies that whatever system you're advocating for must force people to prove that they're poor. These requirements don't come out of the sky and get magically enacted by some fairy, they're gonna be an active by bureaucratic process. That's a non-starter because then the system isn't universal anymore. It only serves people that are able to reach that bar. The poorest and most destitute among us, lack the ability to produce documentation. Many are disabled, uneducated, destitute, have dementia, or any number of other problems that affect the people who need help the most.
It should be easy for anyone who's paid into Social Security to get their benefits back out of Social Security. They shouldn't need to prove anything else.
The easiest situation is to just force people who make more than $176,100 to pay their fair share.
