Grocers are the biggest boosters of SNAP because they are the real beneficiaries of the SNAP funds, in more ways than one.
The food retailers can charge higher prices to everyone, when half of the customers are getting their food for “free” and couldn’t care less what it costs.
The flip side is, these same retailers can depress wages for their employees, because food stamps and other freebies are available to subsidize the low wages.
The low-wage employee pays less into Social Security, and because SNAP benefits are not considered income (even though it is) it’s not subject to SS taxation. The employee eventually realizes that this was a bad deal all along when it becomes time to draw a tiny SS check.
Mean while the employer immediately saves more bucks by paying less in SS matching funds, as well as wages.
