I disagree. Social Security, or the premise of it, depends on a lifetime of work. Of earning a paycheck, paying your way through life, of paying for housing, raising a family, making sacrifices in order to save now, so that you might be able to enjoy your future...when you can't work because of older age.
I don't think most young adults recognize what Social Security is, because they haven't worked enough, paid enough taking care of themselves or their families. They don't yet appreciate that they too, will be old someday, and that they may not be able to physically or mentally work.
Because they don't yet recognize what retirement is, what Social Security is (and let's face it, SS is not a magic bullet for retirement), they can't yet appreciate what it would mean to have a reduced, or even no SS benefit when they retire.
If I heard more of the millennial generation saying, "you know, I'm putting 10-15% of my paycheck into my retirement savings, and I'm contributing another 6.5% to SS...it'd sure be nice if I could see some of that when I'm ready to retire!" -- If I heard them saying that, then, I might feel sorry for them.
People can’t afford to save money for retirement. Especially when married. One spouse may want to but the other basically makes the decision by spending all the money as rapidly as possible.
Most people under 40 today will die at their desks.
Are you joking? There's not going to be SS benefits for Millennials. Millennials aren't going to retire. They'll work until they're dead or hospitalized. They might as well enjoy life now.
