Why has British telly developed a depressing taste for getting the rich to meet the lumpenproletariat?

Perhaps I'm missing the point (or is there really one) - but sending loaded...and ex-royal personnel to places like Wythenshawe, Liverpool - and other points north of Watford (ho hum...), with the latest outing being a council estate in the great city of Leeds makes me wonder who are the beneficiaries. At least actors in dull soap operas, whiny pop singers and line-ups from the old and new 'Strictly Come Dancing' - with a couple of telly chefs need not worry when their particular roads come to an end, as the many estates - as far north from London as possible (but of course), will await them, with sheets of patronizing guff for them to throw at the poor s who've been given the 'privilege' to meet them, and be 'helped' to be 'better' people.
