It isn't a case of differing, Joel; I am right and you are wrong.
No, seriously, nobody familiar with the situation thinks it can be fixed, let alone easily. The math simply doesn't work, and never has.
And while I agree with you that it should have been addressed long ago, I must point out that Democrats virtually never have proposed viable ideas, and when Republicans have done so, Democrats have accused them of shoving grandma down the stairs, etc. The last time anybody tried was Dubya, and you know what happened to him. The last substantive changes were ramrodded under Reagan, with help from Tip O'Neill, and as soon as they were passed, the Dems went on their usual attack and the GOP suffered in the next election.
Obama had a twofer. First, he completely ignored the recommendations of his own blue-ribbon commission, chaired by Alan Simpson and Erskine Bowles; then, he joined Hillary Clinton and Bernie Sanders in making the Democratic Party take the position of increasing SS benefits, just the opposite of what needs to be done.
