Walmart would be employing these workers even without them receiving welfare. Have you ever lived in a developing country? If you have, you'd know how little people can subsist on and continue to work.

In fact, without welfare, and programs like SSDI - which when it started in the 1950s, accepted only 200,000 people as a result of strict eligibility requirements, and has since grown into a massive social welfare program with over 10 million beneficiaries - far more people would be applying for the jobs offered by Walmart.
