The first one: in relation to what the life of a medieval person was, today all artists are born rich.
Today someone can have a day job and enough free time to pursue his/her art.
In the medieval time, either one was a full time artist or a full time something-else.
You have been watching too much popular tv.
"The first one: in relation to what the life of a medieval person was, today all artists are born rich."
Totally false analogy: what was bought for less than £ 30,000 in the early 80s is on the market today for over £ 320,000. In many cases, the same buyers could not afford to come close to the asking price today. Relative wealth today is not related to relative wealth back in the days of the Borgias.

You can't serve God and Mammon. And for those who try, the word amateur and/or dilettante applies more readily than does artist.
But the basic point to which your post referred wil always apply: people are born what they are. As they say, clip Cartier onto a pig's ear but it remains a pig; hang a Hassy around a philistinian neck and the content of the head it supports hasn't changed an iota.
