Quite. Kate Middleton won the “lottery” (and I use the word ironically as not one I would want for myself or my daughter but if you like that kind of thing she did “well”).
There must have been hundreds of other wannabe sloanes who also tried to push themselves into his circle, she was just the one who pulled it off.
On the other hand it’s very clear that her parents were ruthlessly ambitious and left no stone unturned to marry their daughter to a prince.
I can’t work out whether I am more impressed at their single mindedness or depressed about where they chose to focus their energies for a girl who clearly had a lot of potential to achieve things under her own steam.
