>we no longer have a service based economy, but that we now live in a jester-based economy.
In which way jester-services is worse than any other types of services?
>Science isn't necessarily flashy and loud, it's a lot of hard, often thankless work.
And in most cases it is more useless than the work of jesters
>society has a lot of other roles that need to be filled, but if everyone only wants to be the star, a lot of roles just won't happen
We do not live under communism, so "everyone only wants to be the star" does not imply that society is obliged to fulfill this desires. The market will fill these roles even if everyone wants to be the star.
