> But making reductionist blog posts on the internet in an attempt to justify your own urge to write people off as morally bankrupt solely based on their finances
The author's intent is to highlight the errors in a NYT video. He's not attacking poor people.
I may have made a leap with that statement, but if you look under "Why Is the U.S. So Much Richer?", he practically lists out the entire Republican platform as corollaries from this one point. Given his unabashed political agenda and the overall point he's trying to make here, it's not a huge jump to assume that he sees the problem of poverty in America as overstated, self-inflicted, and generally not worth making a coordinated public effort to solve beyond proselytizing his personal lifestyle choices including reversing "changing attitudes toward sex [and] marital fidelity" (???).
And what constitutes to riches when you make no income? Does the burger you eat out of the trash mean you're better off than someone who can only stuff dirt in their mouth? Yes, but which nations are actually full of poor doing that? And is the available food waste for consumption really a good and valid indicator of relative poverty?
America's poverty situation and cultural challenges are extremely complex. Nobody chooses to be poor. Plenty of poor people - I'm sure not every single one of them - aren't able to change their situation despite plenty of hustle. Welfare alone isn't the solution. But making reductionist blog posts on the internet in an attempt to justify your own urge to write people off as morally bankrupt solely based on their finances isn't helping anyone at all.
