Several years ago I considered starting one. Didn't understand it at all. The HR dept where I work had closed and to start a 401K I had to do it online. It was so hard I gave up and never did it.
Yesterday I learned from someone at work that the 401K plan tanked and everyone lost their money. $30K to $40K in just two weeks for most was gone.
Is that really possible? If it is, my ignorance has been my savior.
