The content of the article shows that it is still a problem. You think that landlords and food suppliers colluding to raise prices to just below the breaking point is not a problem?
It's not a "breaking point", it's the market rate. There's no landlord cartel; anyone can easily defect and lower their own prices.
The entire food production and provision supply chain has razor-thin margins. If you're hyperfocusing on that industry, it's a sign that your heuristics are pointing you at the wrong things.
Outright monopolistic pricing is also "the market rate". Frankly, virtually any price somebody is willing to pay is almost by definition "the market rate". It's a meaningless defense for an artificially high price.
