That seems like a little bit of a cherry picked article to support your point. Scrolling through the front page of that website the top article is an opinion piece by Joe Biden which writes about the importance of supporting young people and those out of work:
"So we need to make sure that our economic recovery does not come at the expense of those who can least afford it or who are just getting started in life: Hard-working young people in service industries and retail that are being decimated by layoffs; all those who are hustling to make a living in the gig economy, and those who were already struggling to get by before this crisis, who are drowning in credit card debt or student loans, and who now are in even greater need of a lifeline."
When I scroll further down the page I can see a fundraiser for readers to support "people and communities who are more vulnerable and need extra support during this time" including the National Domestic Workers Alliance, Restaurant Workers Community Foundation, and One Fair Wage. Apparently readers and podcast listeners have contributed about $650 000 which at least from an Australian perspective seems non-trivial.
Finally, one of their most recent articles (I'm going through the articles because I'm not going to listen to the podcasts) on the politics of a pandemic titled "How Democrats Should Navigate Pandemic Politics" talks about the importance of directly supporting workers including with "paid-leave provision that’s much bigger than the one the White House watered down in the initial House bill, along with a broad Emergency Unemployment Insurance provision".
I can't reconcile all this stuff with being blind to it. It looks like the founders of this site were in the white house while the medicaid expansion was passed which, at least from an outside perspective, seems to be the most important legislation of the past few decades for the poorer working class.
Even that article you linked to doesn't seem like a damning indictment. If you read it a bit more closely it's at least partially a joke article where the writer talks about the resilience of the human spirit while writing on the walls in lipstick, getting gum in her hair, and napping in the middle of sentences. If it was a manifesto of values I'd agree with you that a lack of focus on unemployed people undergoing hardship would be notable, but it's not. It's just a joke.
