Some of those are a little odd.
53% of the public support the government hiring
everyone who is unemployed?
Also, it's a little misleading to include the poverty line numbers. It says "no family". The current minimum wage is actually well over the poverty line for one person (which is just under $11.2k/yr, whereas the current minimum wage at $7.25/hr is $14.5k/yr at 40 hrs/wk, 50 wks/yr), and only just a hair under the poverty line for two people ($15.1k). Whereas having a minimum wage such that single full-time wage-earner could support a family of 8 at the poverty line would require the minimum wage to be set at more than $19/hr, surely beyond what the system could support, and even higher for supporting larger families.
So, how many kids are we talking? I could see the minimum at the point of a single parent working a minimum wage job supporting 2 kids at the poverty line (a minimum wage of just under $10/hr, incidentally exactly what's currently proposed), but more? The real problems there are single parenthood and people having more children than they can afford, not the minimum wage.
