I think the billionaire lifestyle on a multi millionaire income should stop, because it isn't sustainable. Even if up to the last few years Harry has never known anything other than international fame, access to multiple stately homes and life being smoothed over for him and Meghan is going to accept nothing but global superstardom or bust, a true step back and reevaluation would not be the sign of failure they seem to think it is.
They've mucked up royally (sorry) but I believe there are ways out of the mess, if they choose to do things differently. I don't think they will though, however coruscating the Press, because seems to be a bunker mentality in play and it isn't healthy. They can't beat the rest of the world into adulation and seeing things their way, but I'm pretty sure they will continue to try.
