I think part of the problem may be that a lot of people use the "half full glass of milk" mindset when it comes to people living below their socio-economic status, and "half empty" when they look at themselves.
It's been mentioned a few times that people below the poverty level have air conditioning, "flat screen" TVs, microwaves, cable, etc... and yes, those things can all be lived without. These are things that have become normal by most standards in the US, but are extravagances in contrast to the people who have no water or food supply that we see in impoverished nations.
A few years ago, TV went digital. Those without cable had to buy a converter for their Tv to work. The Govt accepted applications and issued coupons to get them at half price and you could buy one anywhere. The coupons are no longer available and the converters are hard to find, probably online only. No Internet connection? No credit card? S O L for you.
Can a CRT-type TV even be found anymore? It's funny how the "flat screen" gets slipped in front of TV to make it sound extravagant.
That whole "flat screen, microwave, air conditioned" line comes straight from a radio show I catch occasionally, and he probably read the same "welfare queen" fueled source that was read by posters here.
As you can tell, I'm not comfy being in the bottom percentile, and no, I can't really do anything about it because I don't have the brains or physical ability. I do find comfort in knowing the difference between "you're" and "your" though.
