>>Also, most poor people (78%) don't have even one job, let alone two (nor are they even looking for one).

First of all, that isn't right from the data you linked to. 59% of people below the poverty line don't have a job or aren't in the labor force(Table 6). Secondly, it turns out that not everyone in a family is a wage earner so there is no way to extrapolate from that data point to how many are just living off welfare.

If you look at table 1 in the bls report you can see that those in poverty & and in the labor force without a job were 17%.
