Nope. Food deserts are a thing, but the causes of them are highly disputed. There are plenty of reputable studies e.g.
https://academic.oup.com/qje/article-abstract/134/4/1793/5492274 that posit that food deserts are a function of demand, and that a lack of availability of good quality food is driven by a lack of demand. It therefore follows that should something happen to impact the alternative supply e.g. junk food pricing itself out of reach, demand will need to be satisfied differently.
It can't all be "evil corporations crushing people", because to believe that would be to believe that people are completely without agency and that isn't true, especially en masse. Western, and particularly American, attitudes towards food and nutrition are completely fucked up. Something needs to happen to change that, and while Wendy's charging an extra $2 for a burger at dinner time isn't going to be the catalyst for that change it certainly can be part of it.
