Sadly, I know many people who fall into this category. There's so much more to life than "stuff" and money. A rich life is when you have a home and family filled with joy and love and memories! Money just buys you other places and things not true love!
This is true. Few jobs require that you 'maintain' a lifestyle, especially a luxury lifestyle. You can wear a suit. You can drive a nice car. You don't need the priciest car, and the most expensive suit.
