&gt; They actually have enough money to pay for goods and services that save them time.<p>I think you are missing the point. There isn&#x27;t a magical device the upper classes buy that saves then time (maybe this is the case for poorer people, e.g. having a washing machine is quicker than washing clothes by hand), but once you earn so much, get comfortable and achieve your own level of success, you start to value things other than money.<p>I assume the $75k refers to somewhere where you can afford the mortgage on a nice house, a car or two, eating out a few times a week, and saving for your children&#x27;s college fund, etc (i.e. all the material things society says we need). Once you are able to afford all that maybe you start to value the time you spend with your children, so spending an extra hour communiting to get $10k more isn&#x27;t worth it.
