I grew up there until the time I was 16. The locals were nice, but they despised Saudis who were known as lascivious as well as holier than thou to the level of oppression
The surrounding emirates are often depicted as hating the Saudis.
However, they have all lived together for many eons and have learned to get along, for better or worse. Some of the Gulf Arabs might have been a little envious as the Saudi Bedu were some of God's poorest people. Now with their wealth they do hold all the cards.
Another point: Saudi Arabia has AT LEAST another 200 more years of petroleum and natural gas. One of two of the emirates have already run out of the liquid gold.
As for "lecherous," please, that does sound so trite and envious. The NICEST husbands, brothers, uncles, etc., are not always "nice" when they get too much liquor under their belts.
Also, as ALL THE FOLKS OVER THERE KNOW, the KSA has to be uptight and moral, whether they like it or not because MECCA is there. The rest of the folks in the emirates KNOW that too, so their bellyaching at the demeanor and behavior of the Saudis sounds like simple bellyaching.
I think MANY female relatives would be SHOCKED at the behavior of their male relatives if they saw them "off the leash." The Saudi "leash" is the tightest because it is the home of MECCA and MEDINA, two if Islam's holiest sites.
It's not more complicated than that.
Btw, good morning!
