I find comments like this interesting because they're devoid of the details that matter.
What's the size of the household? Could a single person in rural America making $50,000/year save up enough to buy a house? Sure. Could two adults in a $50,000/year as a household? Possibly if they're very frugal. Two people with 1-2 kids? This is where the situation changes dramatically.
You can't get it in high cost states like CA, NY etc...
