My wife and I work hard and both enjoy gaming. We budget our finances appropriately and have done a lot with what we have. I came from nothing and worked my way up, made wise investments and didn't piss my money away. Since I don't care for expensive cars or fancy clothes and since my wife doesn't either (including jewelry), we do pretty well on savings.
If that makes you stereotype us in some outlandish way, then that's your problem. It's not like I wasn't in your shoes before I got a good job. But even back then I would just budget carefully and buy consoles when the savings matched the price. It's all about priorities and the amount of effort you put in. If you have crippling debt or something like that, then yeah, that's going to be a problem. But at this point we have two houses and multiple consoles from every generation, and make less than $100k combined. So it's more what you do with the money you have than whether or not you're richie rich. Also, had one of our passions besides gaming been particularly expensive there would have been competition for the funds. But that's what my wife and I do when we get home. Watch TV and play games.
That being said, our ability to afford the systems doesn't mean we automatically get them. For example, why would I get the XBO when all of their exclusives show up on the PC? I also haven't picked up a WiiU because I consider it a bad purchase. The console is basically a Nintendo game's tax so when you consider the cost of the games you have to divide all the games you want by the cost of the console to consider if they're getting the console for. Since there are still less than 10 WiiU games I want, the $300 console price tag would add more than $30 to the price of every game which isn't something I'd be willing to pay for.
Remember also that some people are dropping thousands of dollars on all the consoles each generation to their detriment if they can't really afford it. Gaming and collecting them all could certainly be an addiction if you had that kind of console hoarding mentality. We're fortunate that we just want to make a wise investment with a high return in entertainment rather than just trying to collect things we'll never enjoy.
