Being tan is desirable for the upper class, because they're trying to avoid being seen as middle class "toiling away in offices", and don't particularly care about being confused for lower class.

Being pale is still desirable for the middle class themselves, though, as they're trying to avoid being seen as lower class (tradespeople, farmers, etc).

Also, thinness is actually a middle-class obsession, because it's the lower class who "don't have enough free time to go to the gym or take vacations in warm places." The upper class don't care what their bodies look like, as they all know that they and everyone else in the upper class can afford to "throw money at the problem" (plastic surgery et al), and so how healthy you look is no longer a good signal for how healthy you actually are. (Instead, they tend to judge your genetic fitness — when they care about that sort of thing — by the health of your lineage, going back several generations. Which is one reason royals/nobles make a big deal of keeping track of that.)

>".... farmers..."

[Dystopian Aside]: I have been saying for a very long time (rightly/wrongly), but always been laughed at; "In the future, the most valuable people will be farmers"

I was laughed at.

However, look where we are headed. Right now, today ; BGates is not only one of the most famous and richest people on the oblate spheroid, he is also the richest "farmer"[0] in the world.

The "farmer" ([0]:pharm-er) who masters lab-grown civilization-supporting-scale sustenance production will be the richest in the galaxy.

Ever try to corner the galactic wheat production in Trade Wars on BBSs in the 1980s? Yeah - we are at stage zero of seeing that in action, and it wont be pretty.
