Yeah, you're right that is the only alternative - there is nothing else possible. Did it hurt punching that straw-man?
There are many alternatives with better results - for example, why pay benefits to those who already have substantial retirement incomes?
Why not limit payouts to those who are truly needy not merely elderly (which isn't the same as needy)?
Why not accept the reality that since most people live longer, healthier lives (increasingly after eschewing raising children who would have supported them in their later years either directly or indirectly) that they must work a few more years before expecting any government financial aid?
You may have better ideas than those I listed but the Ostrich plan isn't the one I want in place when I hit 70.
I'm sorry if you think I was trying to "straw man", I wasn't. It's just that it seems all we hear is cut benefits to the elderly. We certainly don't hear about cutting benefits to women who have multiple kids when they're already in poverty. And we don't hear talk about cutting EIC, child tax credits, etc. for people working who couldn't afford to have kids and maintain their standard of living.
And I pretty much agree with the ideas you listed.
