Let me flip that argument on its head-Retirement age should NOT be raised. It is 67 now. Asking people to give up 36 monthly SS checks because the wealthiest amongst us refuse to pay SS tax on ALL their wages like the rest of us do is unacceptable. What kind of people are that freaking selfish?
EVERYONE can save enough in 40 years of work to self-fund their own retirement. What kind of people are freaking selfish enough to not save their money and then expect others to cover them?
Now, please understand I am not really arguing that literally. But there has to be some kind of balance so you don't end up incentivizing not saving and not working. The hard part I suppose, is everyone's take on where that balance is is different based on their own experiences and beliefs...
