Eugenie appeared to have always been on a particular career path in auctioning art since her early days of college. And in fairness to Eugenie, there haven't been rumors that she believed she would be a working royal during college. I'm not even sure she ever wanted to be working royal.
Beatrice, allegedly, assumed she would be a working royal when she was younger, but there is no evidence that the Queen, Charles, or William ever gave her a reason to assume that. In fairness to Beatrice, there have been many sources claiming that her parents, who had no authority to promise her anything, told her all her childhood that she would be a working royal. I do feel bad for Beatrice, but I don't think the blame lies outside of the House of York, unless something happened that has remained secret so far.
I had forgotten about the tabloid articles of Beatrice yachting and traveling while allegedly working for a London or New York-based office, but you are right, they did exist. I just think the decision not to make Beatrice a working royal was firmly made years before those tabloid stories occurred.
The tabloids were awful after William and Catherine's wedding, and I will never understand why someone advised the girls to wear those hats and that makeup. The hats got more attention, but their makeup made it so much worse- it looked like it was put on with a trowel- two fresh, beautiful young women at a daytime wedding with makeup meant for a nighttime drag show. The girls were still young and understandably trusted the wrong people at that time. The timing was especially bad, as the alleged meeting with Charles took place a few months later, but I don't think there was any plan to make Bea a working royal before W&C's wedding anyway. At least, there has never been any proof that Charles or the Queen had any plans to do so,
But I think their reputations have never been better than they are currently. In fact, I think it's the tabloids today that are currently driving the premise that they should become working royals- the opposite of 15 years ago.
