When I first invested in my 401k, I had no idea what to do or where to learn. I think I put half in an S&P500 fund and half in a mid-cap fund. If they're going to give people the freedom to choose, they should help them learn how to make sensible choices.
Same here. I was 24 in 1981 when I first started my 403(b), the woman in HR asked me how I wanted it split and I guess I must have looked like a deer in the headlights. So she said, "Most people split it 50/50". I now know that I should have been in 80% stocks and if I had, I'd have a lot more in my stash than I do. I literally just set it and forgot it. For decades.
I think that's the biggest problem for the boomers. They're the first generation to have almost total responsibility for their retirements; their parents for the most part had pensions. But we do an abysmal job of teaching financial literacy including investment skills in this country, so most people follow in their parents' footsteps. And in the case of the boomers, their parents never thought or said much about retirement, it was just there when it needed to be.
Add to that the jargon of investing (as with any other specialized field) that the experienced people on here use and my head just spins trying to keep track of what it all means, how to make smart decisions and what the consequences might be.
