I also have socks with side indicators. They’re designed to fit the feet, so the entire socks are asymmetrical. Theoretically you could go by the pattern, but when you’re pulling socks out of a hamper it’s a lot easier to match them via letters which you know are always at the ends. It’s pretty convenient and makes it impossible to match them incorrectly, so I think it’s a good design choice.
Just to offer another perspective, this covers just how difficult the burden of administrative tasks already is for physicians: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8522557/
Not all physicians work for a hospital, so I don’t think they all have much access to large departments that can take up the slack for them. It’s difficult to ask them to chase our insurance for us when the paperwork they already do is driving them insane and taking them away from their patients.
The solution, as you said, is single payer. The overwhelming administrative overhead is a symptom of a very broken system. Nobody directly rendering or receiving care is benefiting from how things currently are in the United States.
