Do they? Or are things like food deserts transitive symptoms of deeper problems? E.g. that the surrounding area is poor and getting poorer. If so, no amount of legislation will change that
Programs like SNAP, the earned income tax credit, subsidized child-care, and refundable tax credits for children have an immediate impact. Legislation could also provide a universal basic income.
If that's too pink a set of approaches to reduce the impact of poverty for you, governments can also subsidize development of new housing and invest in infrastructure upgrades that draw folks with higher incomes into a community. This works best if you are in a metropolitan area. In rural communities, it's not uncommon to pour great sums of money into courting large employers, giving them land or tax free status for extended periods.
Hell, if your goal is just to get a grocery store, pour on enough subsidies and someone will show up to collect that money.
The more money there is to be made in the grocery sector, the more grocers there will be to compete for it, located in the places where the money flows. Likewise the leaner they have to operate, the more they'll shut down in marginal territory that can't support their business, and the more areas will go without convenient access.
If selling groceries in low-access areas for low profits is indicated by the necessity of food, then nobody is stopping you from doing it; but as the grandparent comment hinted, if you find your niche in high-margin software instead then you're following the money, just like grocers do.
I don't think we've seen that scope here in the US... Yet. But given the number of guns, "it's a when, not an if" if the politicians allow extreme food scarcity to happen in a wide area.
panem et circusensus (bread and circuses)
The way I see it is that any food desert either exists because it is not profitable or because nobody has taken the initiative to offer a profitable service. Obviously I could be wrong, but I have a hard time seeing how a megacorp is denying access to food.
Kroger et. al provide no unique value - they don't have any intellectual property, they have almost zero human capital because they treat their workers terribly and have low retention. They do some stuff with their private labels but that's really it. What grocery stores doing that commands more than a 1 or 2% margin on a huge segment of the economy? If they're earning more than that it is probably and indication that they are ripping off the consumer, ripping off the worker, or both.
They are not earning more than that. Kroger's net margins were 1.7%. That was the entire point of my post.
Ah yes, it's important to remember we should only care about ourselves.
Kroger's most recent reported net profit margin was 1.7% with gross margins (e.g. before company expenses) in the 22% range.
Compare that to the SaaS companies, where many of us collect our paychecks, that can have gross margins in the 60-90% range.
If you want to call companies out for price gouging and excessive profit margins, taking Kroger to task for a 1.7% net margin seems kind of silly. Especially when most of us engineers are collecting paychecks from companies with far, far higher margins than that.
