I think it is a combination of a few things that have ended up with them both looking like lazy spoiled children with no direction and little talent or ability to their name.
Neither also seem to have any real friends who have the ability to see how they really look to everyone else
Pretty sure they think everyone is jealous of them.
The problem with having no talent, no ability, no focus and nothing to occupy their time is that they have all the time in the world to think about every word that has been said to them and find fault and nastiness in the most innocent remark
I would say that there is probably some misinterpretation between how American people talk to each other and British people talk to each other. Add that in with someone who is painfully aware he married up and will do anything to keep his wife and her billionaire family happy and he will cut off his own family to please them.
I would say the next thing to occupy them is having a child or getting a divorce. Hopefully his family will take him back if they get a divorce. If not I think it will be a rude awakening that he has to work to put a roof over his head (presume there is an iron clad pre nup)
Being lazy, having no talent, an over inflated ego as well as having not a clue how the world works aren’t exactly qualifications for any job.
However judging by his CV there is one place he could get a job
