Yeah, the lack of education on finances, investing, etc is a terrible thing. I hadn't even heard of an IRA until I was in my 30's, I barely knew anything about stocks and bonds--and any talk of ETFs or mutual funds might as well have been a foreign language. I had to really self-educate, fortunately there are a ton of resources out there now for free that you can learn from on the internet but you have to go looking for it. It's no wonder you see articles out there all the time about the high percentage of Americans with little or no retirement savings.

I don't know how someone in the 55-64 age range can even think of retiring with around $200K in a 401K unless they have money stashed elsewhere. I invest for tomorrow much more than today and admittedly I am lucky that I will have a pension, a Roth IRA and a 401K when I retire. I do have a taxable brokerage acct to play with but I only put money in there if I can afford it after my 401K and Roth are maxed out.
