Actually, Marie Antoinette only was queen and had no power over state matters, as that power was purely invested into the king's hands, thanks to policie taken by Louis the XIV.
In fact, even her statement of "let them eat cake" has been debated over, and more or less people realized she meant it as "can't we give them cakes cause we gots a butt ton in the palace?"
If you really want to know why France went to shit right before the Revolution, look into the reign of Louis XV.
That being said, do realize that nobles are first and foremost soldiers; they were awarded titles and land, as well as exemption from taxes, in return for using that income to raise a force as well as lead said force in battle. Countries with longer periods of peace have low numbers of nobility (France having around <1% of the population), while those that experience lots of warfare tend to have proportionally more.
Additionally, stories about aristocracy are either aimed at "commoners" to gain popularity, or for propaganda reasons such as the Renaissance era writers trying to make the previous Medieval period look like a shithole in history.

You do realize that Kim Jong Un grew up in Switzerland and attended classes there? He's been confirmed to be a basketball nerd and idolizes Michael Jordan, and was apparently a PC gamer.
