I thought I'd help out with some figures I found for 2013. They are supposedly supplied by Wal-Mart to help in attracting applicants.
This chart shows wage ranges for each job title at Wal-Mart. These show the starting hourly wage (low figure) to highest wage attainable for the position. Note that for the four positions shown in your chart there is some slight increase in starting hourly wages, based on eight years inflation. Not much of an increase though, right?

Seems like in some positions people are getting a decent starting wage? It might until you look at this second chart which computes hourly wages by experience in the job. There you see a starting average of all jobs of $8.81. It takes 1-4 years to go up $0.58 to $9.39; 5 – 9 years before the average goes up to $11.00 (increase of $2.19); and 10 – 19 years before it goes up to $12.13 (increase of $3.32).

Then we see average hourly wages by state which shows the average hourly wage for ALL Wal-Mart employees is $10.46 regardless of time in the job. At 30 hours per week on average a full-time employee earns $16,317.60 a year gross ($13,914.57 after taxes). Part-time at 20 hrs per week earns $10,878.40 gross. The current Poverty Threshold for a single person is $11,945.00 For two people (married) it is $15,374.00.

Conservative is correct about one thing, after 90 days employees get a raise. I understand this is about $0.25 /hr. Wal-Mart also pays (according to this site) 1% over the average rate for such jobs.
HOWEVER: Full-time Wal-Mart employees still work 28 – 30 hour weeks, Part-time less than 21 hours. The above figures don’t account for Wal-Mart’s practice of requiring unpaid “voluntary overtime” for non-scheduled hours, or frequent last-minute reductions in scheduled hours to meet monthly budget limits.
Wal-Mart still instructs their employees on eligibility for Medicaid, Food Stamps, and Welfare services.
