I really wanted to be crass, crude and blunt but I can't.
My country in particular is an exporter of healthcare workers, thanks to a neverending cycle of bad management and low funding from and for the Health Ministry.
University tuition is less than €2000/year for medicine, nursing and physical therapy. Other healthcare related areas are even cheaper. The notion of university loans exists but it is a rare occurrence.
Edit: I got owned by myself; the yearly tuition is €697, payable in full or in ten instalments. That's affordable!
We are undergoing a shortage of labour due to the state not wanting to pay more, which is moving workers to private healthcare where they can work less for better pay.
There is no shortage of labour, there is a shortage of money flowing to those that actually work for it.
