Walmart jobs were never meant to support an entire family.
Most UPS jobs do not pay enough to support an entire family.
One person - yes.
Family of 4 - marginal
Unless one lives in a "bubble of happiness".
Of course, the real problem is people thinking they are entitled or deserve to live a life-style above their income.
I know people who get by on less than $20,000 / year.
They drive older (older being 15 or years) cars,
they have a flip phone using Tracfone and/or do MajicJack VOIP,
they get broadcast TV (no cable or satellite) or absolute basic package on cable/sat,
no iPhones or iPads,
a few use internet access from their neighbors wi-fi or go to McD's or the Library,
They rarely eat-out,
they use coupons at the grocery store,
they don't have health insurance (Obamacare will hopefully help),
they don't take vacation except to visit other relatives,
