I'm sure Harry was convinced he was 'Trapped' by Meghan. He has had a varied career and was given much more freedom than William was.
William is not trapped -he works (or worked) outside the Military piloting an Air Ambulance.
Charles is not trapped, he has the thriving business, Duchy of Cornwall, to keep him occupied.
Meghan probably felt trapped in that she thought being Royal would be floating around a palace barking orders, and doing whatever she wished, followed by her 'Security'. When she realised it was not actually like that, then she had to formulate a Plan. She knew she could have status in La La Land far higher than even the most A stars of A listers, because she is a Princess. So then began the grooming of the multi-millionaire Prince, now husband who could provide all that.
Harry needs a wakeup call with a couple of weeks in a high rise flat with two kids in total lockdown. Then he might realise what 'trapped' means for some, and how utterly foolish Megan is making him look.
