Did something change in the regulation or cost model to make pharmacy deliver unprofitable? Medicare/Medicaid too expensive? Less demand for Pharma services? Not sure of the driver -- there are a lot of points one could evaluate.
You can look at the history of Bartell Drugs in WA. They were sold to Rite Aid, Rite Aid went under because of them being a shitty business and so most Bartells have closed down or are practically dead. And without replacement, that means there's now fewer pharmacies and the ones remaining are understaffed and overworked.
In the 80s the local pharmacy was your primary source of sundries, towns and cities alike. Everything from hardware to toys to medicine. If the local pharmacy didn't have it, you didn't buy it.
Now with hoards of Chinese shit available at your fingertips to order with same-day delivery, pharmacies couldn't survive on selling medicine alone, of which there are very small margins.
San Francisco and other cities making widespread theft and shoplifting de facto legal didn't help either. Local mom & pop pharmacies can't afford to put the entire store behind glass.
Why is a solution needed if the people it supposedly impacts hardly care?
