I guess it all depends on how wealthy one is, and how much disposable income he has, wouldn't you say?
From what you wrote, I see at least 31K from you in disposable income. That amount represents half of many family's annual income. Not everyone has an IT job or lives in the coastal cities. Not that you do, but I'm just sayin'. Many of us have been in the hobby for a very long time, 20 years or more, and have slowly worked our collection up from the beaters we found to having one or a few nice games, all while running our households and our lives. We have relatively humble incomes.
In the last, say, 15 years, there have been some very wealthy guys who have joined the pinball hobby, buying in high, buying the top tier games, price no object, having a known collection, rare games too, making a splash, walking among the rest of us (or above the rest of us, no insult intended). I have heard of one rich pinballer, maybe there are others, who goes from avocation to avocation, buys in high, get familiar with the hobby, and once he figures it all out and does all that he thinks he can do, he gets bored and moves on to some other hobby that he has not conquered yet. I can't decide if his situation is enviable or even has to be.
Is it possible that the pinball hobby eventually increased in value just enough to have approached your activity level, making you notice it, bringing you into it? For instance, do you eschew hobbies that are truly inexpensive, or does the excitement of high value provide the energy you need?
On a somewhat related note, I read an interesting article where people who grew up in wealthy families explained the assumptions they made about life and the rude shock they learned once leaving home. For instance, they thought everybody had a maid, or a vacation home, or a private plane, or ate at restaurants every day, or never worried about price tags, etc. One example that amused me was a woman who had believed that people who did not immediately run out and upgrade their iphone each time were simply too lazy to walk to the apple store.
