He means the article is saying they will need $3 million in today's dollars to retire
I do believe that would be 30k per year.
I assume you mean $30k per year. The recommended is more like $700,000, and that factors in your pension, but we're just using approximate figures here. Still, $30k per day today is quite doable for a retiree. What are you going to spend your money on, exactly? You've already purchased everything you need by that point in life, so you're just in maintenance mode.
