> There are many, many heads in the US, experiencing the same sort of concerns that this guy did. With whom should we have conversations and how should those conversations go?

All of them. And not just via government, or the non-existent mental health authorities, but neighbours, acquaintances, and passers-by. Increase social welfare spending, sure, but also, people should be kinder, more empathetic, and look out for one-another. This could be as simple as striking up conversations with strangers, or people outside our wealth bubble. It could mean volunteering for a charity. We're all complicit in the propagation of bad ideas, and the decline in community, and we can't always lean on systems to fix it for us.
