No, but the alternative is to vote for the party whose policies would funnel trillions of dollars more from the young to the old.
If anything, it's the Democratic party that wishes to preserve programs that funnel billions upon billions of dollars from the young to the old (Medicare and Social Security).
No, because everyone will get old. What the Republicans are trying to do with the Ryan plan is exempt everyone older than 55 from cuts, while anyone under that age has to bear the burden. Either the cuts should be effective immediately (only exempting those already on traditional medicare), or payroll taxes should be cut for those under age 55. I have no desire to subsidize people in their highest earning years just so Romney can win a goddamn election.
a) The average life expectancy is only 78.2 years (38th in the world I learned today). This would imply that there is a sizeable portion of the population who doesn't make it to 65 for one reason or another. In short, not everybody gets "old" (for the purposes of this topic).
b) Regardless of how many people "get old" or not, that doesn't answer the question of why we have two massive programs (so massive that we've created an irreparable dependency on them) that redistribute resources from the young to old, by design.
FWIW, I agree with you on the fine points of the Romney/Ryan plan, especially regarding the Payroll Tax (which I would prefer to be dramatically reformed).
