My youngest sister, hereafter known as Leech, is the champion "must be nice" person. She works as a server in a restaurant, as she has for the past 14 years. The area where she is operates primarily on cash, so the tips get in her pocket the same day, and spent after work. At the end of the week, when she needs to buy groceries or pay bills, there is nothing left. She doesn't understand the connection there.
She just bought the newest Samsung phone, buys new purses weekly, eats out nearly every meal, etc. She is jealous that we have annual passes for Disney World, go on a few weekend trips a year, week long vacations, and that we don't have to borrow money from others to pay our bills.
