And once again you failed to note that in my comment, I specifically highlight Miyabi as an outlier. He ain't your average joe that needs to accept randos' demands and compromise with them. I'm Asian and compromise isn't a magical thing that you have to enlighten people about, its the same everywhere Asian or Non-Asian. If you really think its ridiculous that an extremely competent outlier is sought-after, I think you need to get a reality check because that's not uncommon for top specialists or management in businesses, much less someone like Miyabi who is literally the one-in-a-million person who can revolutionize their whole world.
You feel that MC is an outlier, but it isn't actually.
The only thing unique about MC is his Earth knowledge and his Magical capacity.
Other than that, whatever he can do could be achieved by other Crafters.
Its just that, because the situation and societal position of Crafters isn't good in that World, they haven't been able to develop.
And at the end of the day, it's MC who needs their help, not them.
Because even without MC, they would go on with what they had been doing so far, but since MC has given them the idea regarding the concept, all they have to do is invest in people who could recreate even a fraction of what MC suggested and develop it over years to usable condition.
Basically, MC is just their to fast forward the development, he isn't really necessary for them or their society, as the society would develop by itself slowly given time.
Example being, how they had already developed the Wooden Block Braking technology by themselves.
And if we go by our history, Wooden Block Brakes were invented in the 1800's (which became obsolete in the 1890s when rubber tires were invented), around the same time Trains were invented.
But here they had already invented them long before even the concept of trains came up.
So, it wouldn't be surprising that even if MC hadn't meddled, they would have developed a system to transport and move around for long distance by themselves in 50-100 years from now.
Just because one can revolutionize a world, doesn't mean they are highly sought after, because people like that exist everywhere.
Like even Liz is someone like that, as the knowledge she had developed based on her expired father's teaching and self study is quite revolutionary in the magical filed, which is why she got the scholarship offer. But that doesn't mean she is actually required for it, as someone else eventually might have done the same.
Even in real life, we had people like Leonardo da Vinci, who had created various concept for machinery, including designs for flying machine, but all those remained concepts until centuries later. He was also a one-in-a-million person whose ideas could have revolutionized the world and many people at that time knew about it. But except his paintings, majority remained in the dark for years.
At the end of the day, this isn't a story about showcasing how great MC is with his development work, and how all the people around are accepting of him.
It's different, in the sense that, just because you have knowledge and ability that others don't have doesn't make you a worthwhile person, it what others can learn from you that makes you worthwhile.
