We’re all responsible for our own wellness but we’re also responsible for the wellness of those with whom we interact. The “wellest” person in the world could only tolerate a toxic environment for so long before they’d become unwell, through no fault of their own.

This is a limited view akin to thinking you're doing your part for addressing climate change by staying off the grid.

I agree with b0surk that this is redirection and fundamental changes to society need to take place. Like an end to wage slavery.
