I guess I have to clarify.
My idea of retirement, must be quite different than other people.
If you don't have kids to support and don't want to travel. Plus own your home and your car. Yes, $150k outside of Los Angeles or San Francisco - should be sufficient. For a nice home in California - you could be at/over $50k for just insurance, property taxes, and utilities.
By the same thought : you could move to Philippines and live great for $30k.
In my friends group : $150k a year won't cover the mortgage, property taxes, and insurance. Add food, utilities, house repairs, a little bit of travel, a car payment, things for kids - you are well over $280k.
