It ' s a common sentiment . There ' s an idiotic idea that our super expensive healthcare system is super expensive becauseA . too many government regulations , not the lack of them . B . Superior healthcare . Both reasons of those are completely unfounded bullshit . It ' s a mixture of American superiority complex and free market magic thinking . Even the simplest amount of actually looking into it shows how terribly wrong both of those ideas are . <| sep |> And now there is no such magical academy currently going on . It was merely a trend set by IS , and you are overly dramatizing it . Furthermore , again , since anime was created we got shows that were very similar to previous ones , the situation you mentioned is just possible in the recent years because there are over 150 shows being produced every year . If we had something around one Sally The Witch lookalike show per year from 1970 to ' 75 , when there were less than 30 shows being made , I can only imagine that if there were 150 shows being made , we would eventually have at least two shows that follow the same story archetype as Sally airing together . And taking the role of an advocate of the devil , there are differences between Rakudai , Asterisk , and Bahamut which were noticeable even for someone who only managed to watch the first episode of each one .
