Earlier quoted context omitted.
I think you’ve taken the right-wing bait a little too to heart here. In the US, most young people, most women, and most ethnic minorities are Democratic-Learning, and I’m speculating those are also the groups most affected by poverty.
He's talking about how the rich young twitteratti of the knowledge class have no idea what poverty is, and yes, most of them are politically leftist. The people affected by poverty aren't writing articles bewailing dollar stores, it's the rich people in the process of gentrifying small towns who hate them.
However, extrapolating that to the OP's point of:
> the average leftist/Democrat in the United States has no idea what it's like to be poor and reliant on many public services
really doesn't follow at all. The numbers are clear that really poor people heavily skew Democrat. In summary:
Less than $30k: 20%R to 43%D
$30-50k: Equal split
$75-150k: 33%R to 30%D
$150+: Equal split
It feels impossible to go from these numbers to the Op's conclusion, although I would accept the modification of it to "the average person in the United States, of either party affiliation, has no idea what it's like to be poor and reliant on many public services". Suggesting that's more true of Democrats is simply not factual, the numbers suggest though.
