i don't think we disagree that much to be honest. i just think that a lot of the issues you are identifying (like long wait time for critical care) are due to price insensitivity due to insurance & overutilization. ie. every MRI my parents have is one that contributes to inflexibility in scheduling for truly urgent cases and also raises the price for those urgent cases.
human intensive things like medical care are characterized by diseconomies to scale when viewed from the whole industry perspective and baumol cost disease. overutilization makes the problem much worse
