And that changed with TV (and cinema).
In the 19th century an actor can play in front of one or two hundred persons each day at most. Now a good movie can be played in front of millions of persons. The same changes applies to sports.
Historically “traveling” actors were often looked down on not that differently than say street performers or your Hollywood “acting waitresses” that gets a few gigs a year as an extra.
However the historical equivalent of A list actors would be acting groups like https://en.m.wikipedia.org/wiki/Lord_Chamberlain%27s_Men or https://en.m.wikipedia.org/wiki/Lord_Strange%27s_Men.
And even in the 16th century many famous actors became very wealthy take the likes of Edward Alleyn and William Knell for example.
Things change the reason why entertainment professionals are paid more these days is because we have the ability to leverage their product through modern technology and the fact that the abundance of resources that even developing countries have today allows people to value entertainment.
And no most scientists were not rich by any means outside of a few in the UK many of them were quite poor and were often living on a stipend provided by institutions or private patrons.
And sorry to burst your bubble but A list actors historically became very wealthy in countries where entertainment was appreciated.
Should Apple be taxed more than Google? Should an actor that gets paid 10 million dollars for a movie be taxed more than an actor who’s paid 5? What if the actor that is paid 10 is has 5 times more views just in less valued markets?
Should I who works as an engineer for a financial institution be taxed more than an engineer working for SpaceX or NASA?
And yes it is clear to anyone who studied economics, and more importantly it's really depressing that you are using these populist arguments how about replacing the movie star with a doctor? Is it ok we pay a doctor who spent the better part of the first 30 years of their life becoming one and would spend the next 30-40 years being one more than a worker at McDonalds who's only required qualifications are to not set the building on fire and being able to say "do you want fries with that?"
The sad truth is that you wouldn't find people that are successful and do no work hard even those kardashians that you seem to adore so much.
That's a good question. I personally don't think so and don't pay them myself. But enough people in our society clearly do, and as long as they have the freedom to chose where they spend their money they should be able to chose to spend it on the Kardashians right?
The question of whether (or how much of) the money they accumulate should be taxed, I believe is a separate issue. I think we could tax the shit out of them, but I would caution against the notion of taxing them more than others on the basis that they're creating less "value" than other rich people. There are clearly plenty of people who highly value whatever it is they produce, and to tell those people otherwise seems like dangerous territory (at least it seems like non-democratic - i.e. when you have a government telling the people what to value).
