I am a Gen-Xer at 49 and I don't expect to retire at all. I have had my retirement savings via a 401K decimated twice due to massive losses when the dot-com and housing bubbles burst. I was unemployed for a year in 2009 and had temporary jobs until 2012 when I finally got a permanent job. In those 5 years I have saved $400K by scrimping. I am dreading the day there is another recession and I see that money halved.
If you're able to save $80k/year ($400k/5 years) and you are having trouble figuring out how to become a millionaire, it would be worth your time and money to seek out better financial advice.
