Except if you want to call unions cartels because they negotiate on behalf of their members with employers than anyone trying to barter in business is engaging in cartel like behavior. Its deconstructive because in practice unions only exist to counteract the power imbalance between worker and employer. A cartel in business forms not to counteract power imbalance through collective action but to monopolize existing power.
You might call those origin points irrelevant but they make the world of difference to me. In the absence of unions labor is almost universally exploited. In their presence, businesses are hopefully and sometimes forced to bargain on more equal footing. Thats a net benefit. A business cartel likewise exists to imbalance what was closer to equilibrium and thus is a net negative.
There is a huge burnout process going on. I see so many doctors try to make a business on shark tank/dragons den work or they try to become media personalities.
Many seem stuck because the job isn't what many would expect. They have invested heavily time/effort in study, they have high debt and they have increased expectations from family/community.
Undergraduate medical education in Europe is commonly five or six years so yes, it could really be streamlined. If summers weren’t taken off you could fit medical school into four years. “Weed our and tire out” makes it sound like there are people who drop out of medical school when it barely happens at all.
In Canada .5 dropout, in the US 3 1/2%, in the UK 5%. In Canada there are very few spots so the effort to get in and have a way to pay for the education happens before. Once you are in the pressure to remain is extremely high. But 11% still seriously think about quitting.
The decisions and effort need to be put in early in life. Very few go to college and decide to become a doctor. They usually have gone to college to become a doctor and select schools/programs based on that. For some it starts earlier than highschool.
When you finally become a doctor after the lifetime of work the job may not be exactly what was envisioned but it is too late.
Offtopic somewhat: I know of smart people who decided to started programming, drawing/painting, inventing, writing, practicing law after age 35 and are enjoying careers. I know of no doctor ever.. is medicine that difficult for someone past 30?
