You're not making any sense.
If we had no SS than why would we have to pay into it?
I'm fine with ending SS and not accepting any benefits, but part of SS is the payments that I pay into it. If SS ends, so does that.
Let's break it down for you:
Because he is advocating for higher taxes on the rich, you want the guy in the article to voluntarily pay taxes that other people in his bracket don't pay when nobody else is forced to.
Using your logic: Because you are arguing against social security, you should voluntarily give up your benefits even if nobody else does.
Your come back appears to be that you only want to give up your benefits if social security is ended. In that case his come back would be that he only wants to pay more taxes if everyone has to pay more taxes.
It's the exact same situation! You are being hypocritical and it's not that hard to understand.
Hopefully you can recognize now that telling him to voluntarily pay taxes that nobody else does is just as stupid as telling someone like you to voluntarily give up their social security benefits that nobody else gives up.
