Having a home to live in is pretty much a requirement in any modern civilization, and in America, those homes are bigger in size as well as in rooms thereof, than any other country. For instance, as reported by oecd.org, in their table entitled, "Average number of rooms per household member by tenure, 2018 or latest year available" indicates that the United States is the true outlier of all other countries in comparison, with an incredible "3.8 rooms per household member." It must be recognized, though, that when it comes to rooms, these represent all of the rooms in a given home, such as the "kitchen-room", the dining room, the living room, the laundry room, the "den-room", each bathroom, and of course, each bedroom. So that, in an American home consisting of three bedrooms and two bathrooms, there are probably a total of nine rooms, altogether, for that home.
One might think that with all of those rooms, and with all of that space, that America would therefore be the paradise of places to live in. No doubt, it is a paradise for those few that are at the very top of heap, that have so much abundance, that they often don't seem to even consciously recognize how good that they have it. So too, those so representing the upper class as well as much of the middle class also typically have plenty of room to enjoy their lives. However, once we drop down to the lower middle class, and the lower class, while they too may be in housing structures that contain a lot of rooms, in comparison to other countries of the same income demographic, the quality of those rooms, the quality of the housing stock, the quality of the area that they live in, and the overall quality itself of where they are at, is not even close to being at the same level for those that have the best of the best. In other words, while it might indeed feel good to have space to stretch out one's legs, that in and of itself, is not necessarily a fair reflection that those that have more room in their housing structure, are necessarily in a good place, or that they are happier than people in other countries, such as Japan or South Korea, in which housing space is at a far higher premium. This so indicates that though everything in America, seems to be bigger, it does not necessarily translate into that bigger is always indeed, better.
So that, America has plenty of housing space, but this doesn't tell the complete story, for based upon the amount of poverty that it so suffers from, and thereof the lack of good opportunity, the lack of good education, and the lack of safety so contained within certain enclaves of American cities; clearly indicates that the troubles that are contained within America, aren't really a reflection of the overcrowding within those enclaves, but reflects more accurately the hopelessness and the corresponding lack of investment within that given situation; which may well be exacerbated by the fact that often just a couple of miles away, it is quite clear to the naked eye, just how good everything else for fortunate others so appears to be.
So then, while having plenty of room to live has its place, that in and of itself is not the cure-all for what so troubles America, for what troubles America is its inability to clearly understand that what makes for a good life for all, is an infrastructure that lives to this credo, that all of mankind is created equal, and thereby good governance consists of providing a fair opportunity for all of those people, to therefore have an actual seat at the table of hope, equity, and fairness.
