It's too hard to define "shit wages" as it's a location specific thing. $50k in So-Cal is poverty level, $50k in small town south is solid middle class.
$20 an hour is okay money or absolute shit depending on where you're at.
A nice 3/2 house here is around $150k - $180k. The cost of living here is low, but $11/hr is shit regardless of where you live. $16-20/hr is entry level trades pay. The local Deere plant starts production line employees at $24/hr IIRC.
