Kind of makes sense to me, once you get to a point where you're set. That is you can easily afford the main things (housing, food), plus the extras (electronics, vacations, hobbies) you need a much larger income to "move the needle" so to speak.<p>You still need to work 40 hours a week or whatever, and only get X weeks of vacation. Having a 180K salary instead of 150K doesn't change any of these obligations, or change your life in any significant way, you just put away more money into the bank.<p>Of course, stepping from 40K to 100K in salary is practically life altering. Unless you absolutely suck at budgets you can easily get out of debt and start having real vacations. You can afford hobbies, etc.<p>That's one thing I've always wondered. Unless you can reach super high incomes, the "buy/rent a jet" incomes, your life isn't that different from "all the rest." You still commute to work daily, have a house, etc. I mean sure, the house and car may have higher price points, but the lifestyle is still the same. Maybe I'm wrong and all those luxury brand commercials are right, spending 30 minutes (or however long) per day in a 80K car is so much more rewarding than spending those 30 minutes in a 40K car.
