They've been the political decision-makers most of their lives because there were so many more of them than their parents. And they can criticize Millennials for receiving (?!) participation trophies they handed out until their faces are as blue as their hair, but they've systematically screwed the economy to their benefit their entire lives.
If there aren't enough people in the workforce and wages aren't high enough for payroll taxes to pay more than 83% of their SS benefits, then let them only receive 83% of their SS benefits.
I'm all out of sympathy for their entitlement.
