Under-employed, unemployed ... under the ploy...

I hear these figures: 9.5 unemployed, 16.5 under-employed... But certainly there are individuals who are not accounted for in this country; but just how many is a real mysterious number?! So, 9.5 plus 16.5 equals a minimum of 26% of adults in this country are feeling a serious financial pinch. How do the census people estimate the number of homeless or individuals off the grid though? You have to assume that more than 26% of adult Americans are hurting financially and that an unknown proportion are near to losing their cool over it! I think it's time we stop going by 1960 poverty standards and tell it like it is!
