I agree with the article to a point. I stopped funding my IRA and 401K (before I became self-employed) at age 35 because I started very early and based on historical returns I was going to end up with %7-8 million in an IRA account. There’s no way I need that much money. That would be like winning the lottery when you turn 65. Then what, totally change your lifestyle and try to spend the money before you kick the bucket?
I think once you reach a point where you can safely say that you’ll have a few million in your retirment account, you should probably cut back. I’m not saying to spend the money on consumables, but maybe look for other investments such as a vacation house that you can enjoy now.
