Half the boomers are already at retirement age. Some are more than 10 years into retirement. Someone who has been retired a decade is probably going to have less in their retirement account than they did a decade ago. (Or, given the created Wuhan Flu crisis, significantly less than they did 6 months ago).
You have to start early and live under your means all the way. ‘Under your means’ just means not doing the wasteful things most people do.
I retired at 60, 11 years ago. My net worth has increased since I retired, even with the latest whack. No one will educate you how to do this, you have to educate yourself.
