The UK deal with the royals is really quite different. There may be an over-fascination but there isn't a huge amount of deference, and if the royals want to make things happen that are not popular, they have to use very twisty back door routes. The (public) relationship that even fervent royal supporters have towards the royals is nothing like the (public ) relationship with Stalin et al.

Also, it's pretty easy in the UK to say that the royal family is stupid and they suck and they leech money from working people and nothing will happen.
