Do you understand the economic situation a family can be in? They own a computer whose net worth is about $50. At some point they bought a television. Cable--100$ a month for the fancy kind. The worth of all these things put together is far below the monthly cost of their housing, which they struggle to pay each month. They could sell or stop paying for all of those above "assets" and be in danger of not being able to afford housing and food.
There are places where housing is cheaper. Those places are inevitably situated the furthest distance from locations of economic opportunity. So car and gas and commute, the monthly costs of which dwarf the assets you mentioned.
And let's get back to your claimed 14% who have none of these things. Imagine that--I go to the local thrift store and there's old PCs there that are almost given away (I've donated plenty throughout my years as a contractor--they're barely worth the poundage cost). In American culture, not being connected to pop culture is anathema. Just as cell phone usage has exploded in the poorest countries, in America the first thing parents will provide for their children is television.
It is clear your definition of "barely surviving" is different from the author's (and mine). There's always people chiming in on discussions like this with the "starving children in Africa" argument. E.g. we shouldn't feel sorry for the people mentioned in the article because if you lift their shirt you won't see their ribcage standing out (you'll probably see a bunch of fat from their subsistence on cheap processed food). Are we really a society where that is the measure of how well we take care of our citizens? To me not feeding people is barbaric. Not providing health care to everyone is just short of barbaric. Not carving out societal resources (like public libraries) for shared use, targeted at people who slip through the cracks, is terrible.
Enjoy your data set.
