I was just having a discussion with someone on HN who considered $200k pre-tax to be affluent, and suggested that if you couldn't save $80k post-tax annually, you're doing it wrong. Having lived at $30k, $200k, and now more, I know that $200k isn't as lofty as it sounds. The dollars never seem long enough.
It's all about living a life worth living. Part of that is buying time by paying for services - from remodeling, to plumbing and electrical, to landscaping and tree maintenance, to cleaning.
Once you have a family and sufficient means, the projects that you used to DIY to save money become tasks that you hire out to save time. Do I want to spend the next six to eight weekends building a massive Ipe deck, saving thousands of dollars, or do I want to pay someone to build it in two weeks so that I have weekends devoted to family, friends, and hobbies? Do I want to spend several hours a week cleaning the entire house, or do I want to pay someone to clean it while I am at work?
This can also be applied to subjective enjoyment. Do I want to drive an A-to-B economy car, or do I want to drive a high performance vehicle which I subjectively enjoy driving?
I usually choose buying time and buying enjoyment.
