I was going to compare the GDP per capita between the two countries so I could try and sort of explain why such a policy might work better in a country that 1) has a sort of "make it or you're basically nothing" culture (I think japan has this [and a few other SEA countries]) 2) has such a low GDP per capita that they have the incentive to find work with more money because there are few other options (whereas I could be a lot of things in the UK so I don't need [let's pretend that's in italics] to try and become an engineer). But itd be very long winded so I'll try and keep it short aha. (Though, in all fairness, I haven't actually looked at the labour market in Taiwan and the UK either (probably would've made a good EPQ topic).)
Anyways I understand where you're coming from however the countries are very different, almost too different to successfully compare the success of similar policies (Singapore has a ban on chewing gum and people there are very cool with it, I doubt it would fly here)
And true maybe someone who's only after money might not be as innovative but I actually asked my mate today whether or not he'd train to be a doctor if the government offered him 10k and then 100k once all the training was complete. At first, he said yes, I think most people would've, but then the actual time and effort he'd have to put in got to him and he decided against it. So not only does pre-existing interest block someone but ability too, I mean you could pay me 200k to be a games designer I'm interested but I won't get the job because there will be someone else who is more qualified, has experience, has genuine interest, reads outside of the subject, has the natural capability to do what I can't and that's why I think even if people are persuaded to switch careers the majority of those who end up in those careers will be the people who chose to do so before the incentive and so society would still gain; I think, it might be better to have 9 qualified nurses who do the job and go above and beyond and have 1 nurse who does the job but that's just it, than have 9 nurses who go above and beyond and those 9 only. (MRP falls but it's still a gain I would say; though you might think differently)
In the end, they'll still do the job and hey a lot of innovation comes from someone trying to one up something/ someone or gain money and some come about by accident, not just for the good of mankind, after all I doubt Flemming left his table so dirty for the good of mankind aha
