I disagree with your solution but agree with the problem. We need to find some way to fix this without sacrificing physician education. 3 years of training is not enough. There are other, established pathways with more rapid training for other APPs
Who gets to be a doctor in America is about to change. Trump’s new federal student loan caps will push lower-income students out of medicine and make the physician shortage worse. It's time to shorten medical school to three years. nytimes.com/2025/11/10/opini…
