I've never met Wayne but I spent a lot of time around Walter through some of his relentless charity work, and I agree with this. Walter cared about people, and about Canada, and about Ukraine, and Canada's general position on caring about people including people in Ukraine, deeply. As far as I can see, Wayne cares about money and his rich friends and family, apparently pretty deeply, and not much else. They are not the same.
I don't think Walter was ever ashamed of Wayne while he lived, but I think he might have been now. He was pretty opinionated, but not unreasonably so, and passionate. A wonderful man, I don't think I ever disagreed with him on any particular opinion or passion he held, he is still missed.
Wayne on the other hand needs to show some loyalty and a spine, be willing to speak out in support of his country even if it means going against his current place of residence, burning the cushy job, ditching his no-doubt lovely mansion and his no-doubt wealthy but also very shitty friends, and apologise for his association with some of them, instead of defending it. But I don't think he has it in him. I don't think he gives a shit about this country. I don't think he's torn up about it at all. I think he knows there's more money to be made in the states, I think he thinks Trump helps him make more money, and I don't think he has any interest in seeking the approval of the country that made him as long as there's more profit for him in doing otherwise, and if that ever changes, I think it'll be because the profitability of doing it changed, not because of genuine regret.
