I'm guessing a lot of people on this board are hovering around the 18-30's. With some hitting their late 30's-60's. This isn't for the ones already reaching retirement, this is for the rest of us.

Social security will be dried up years before we get to a point of retirement for those of us just breaking into our 20's. How should we go about preparing to have money to survive after we're replaced in our jobs for being too old? We can't all expect to get tenure, and most of us are going into fields and paths that don't warrant a future of wealth.
