People have the ideas they have about him because of his repeated public statements about matters political - including his ignorant bloviating about Gaia worship even as he flies around on private jets, uses yachts and resides in giant energy sucking mansions.
I pray for the UK that Prince William and not Charles succeeds HM Queen Elizabeth II.
Actually, his homes are extremely energy efficient and he's spent a great deal of money making sure they are.
On the travel, he travels as the government requires him to.
As for his speeches - the media agrees with him on one issue - environmentalism. So, they publish everything he says on that issue.
They don't generally publish his speeches that are, for example, pro military, or about the oppression of Christianity in the Middle East - he makes them. You can find them online if you look. But if you only see what the media spoon feeds you, you get a very warped picture of the man.
