The question was if you could retire today how much would you need.
One response was $2k a week for 50 years. While that equals $104k a year today, it would only be $37k a year in 30 years and $18k a year in 50 years. For me that is not enough to live on.
Now if it was $5 million up front and you could live off the interests without touching the principle. That’s entirely different.
Back to your point, I agree they should have lived on less than they make and saved for retirement. But it’s not that easy.
In the 80’s $40k a year is a lot, the new mustang GT sells for $10. A lot of adults say/think living on $40k a year with paid for house piece of cake. 20/30 years later that new mustang GT is now $50k their $500k paid for house and $40k in income goes nowhere.
My point being trying to live on $100k a year even with a paid for house will be difficult in 30 years.
I get you. Depends on the person, their location, and priorities. Then they don't buy a brand new $50k Mustang GT if they can't afford it. For me $2k a week after tax would be a sweet deal with more than half left over most months. People think they need a bazillion dollars to retire. It's all in the person's head.
