As long as our government is able to borrow over a trillion dollars per year I don't know that a sufficient number of people will believe that, no matter how well articulated.
After a sufficient amount of time passes AFTER the government ceases borrowing such sums, then there will be a shift away from the entitlement mentality. I just don't believe it can happen without the pain and suffering that I see ahead.
I see many Detroits in our future.
Yes, It is clearly headed the way you envision. (And economics being what it is, the break point, when it arrives, could happen very quickly.)
