I think an important thing to note is that he is right in pointing out that his channel was always for people that can move, explaining why you would want to and why he did. The problem is, you finish doing that at some point, and it trails off into "let's complain about cars". There was a video that stuck out to me, where his tone was very harsh and unwelcoming to those who might disagree with him. In the comments, he said something along the lines of "If you find "my tone too harsh" don't watch the videos or deal with it" although I think with more curse words, I don't remember exactly.

I think that's a horrible perspective that he's moved into. As a rather progressive person, including in this topic of conversation, his older videos were a well-measured perspective that I could send to my (rather conservative) family in hopes that they'd understand where he (and I) was coming from. Now, as much as I want to say I like his content and am a fan just because I usually agree with him, he sounds more like a bitter old man complaining in a way that's not going to do anything other than make people who already agree with him feel good, certainly not bring people who don't over to his side or help them understand his perspective. It's all very disappointing.

As far as whether it's "possible" to "fix" North America... I don't think it matters all that much as far as affecting our actions. Whether the things we're doing take hold in 10 years, or 60, or 100, we should start and continue as soon as possible. Being cynical about it, while maybe not being wrong, I don't know, just seems... useless.
