Sure, you prioritizing having a big house over not worrying about having to cough up $5k in even of an illness. Or worrying about losing your health insurance. Medical expenses are covered somewhat by insurance but you're still getting a huge bill if you're significantly ill.
I was damn lucky I could afford it but if I go sick a few years earlier I'd be totally and completely fucked. Of course, if you can't imagine it you can't appreciate it.
We got here by saving together and living in a one room apartment for 5 years. We don't have new cars or iPhones and we go out to eat about once a year (that we pay for her mother offers to take us out from time to time). I just upgraded my 30 inch CRT TV to a 50 inch 4K after a decade of loyal service. Its not for everyone but its certainly not impossible. I make about 43k a year pretax and she makes 37k for reference. Median income nationally is 55k or so and about 75k in my county so I suspect a great many people have the opportunity to do just as we have done.
This was before the ACA though, I don't know how it works now.
