James Lindsay's argument is as follows: swap "the bougie scum" with "the Jews" and "gentrification" with "living in the pod", and both the far-left and the far-right hold the same ideology based around populist ressentiment. The problem with this argument is that it's a silly soundbite-generating gotcha that doesn't address the central issue, which is whether or not we are in a class war. If you're in a class war, then you will inevitably use the language of class warfare, which sounds vaguely like "rich people are keeping me from the lifestyle I deserve".
Both the Far Left and Far Right are in a class war with the 1% and they know it. Is this viewpoint evidenced? Yes, as a matter of fact, it is. From the Tea Party to OWS, the dissatisfaction with declining living standards is bipartisan, and people from younger generations consistently report difficulties with their finances due to tuitional debt and stagnant wages, regardless of whether or not they turn to left-wing or right-wing ideologies to explain the cause of their discontent.
The vaguely centrist neocon/neolib blob that Lindsay belongs to is a group that categorically denies that class warfare is even a thing. From their point of view, you should be happy with your lot in life and just keep calmly eating the detestable shit sandwich of unpayable debts, ethnic replacement, offshoring for cheap sweatshop labor, and shitty, suppressed wages.
What can you even say to a society that promises you forty years of wage slaving in a cuck cube and bars you from marriage, home ownership, vehicle ownership, and upward mobility at every turn, squeezing the lifeblood out of you for no real reward?
Meanwhile, the uber-wealthy are busy building a two-class society of poor, precariously employed, meticulously surveilled debt-serfs and the aristocratic rentiers looming over them who own and operate all the Waymo taxis, automated factories, AI data centers, cloud services, and other revenue-generating property.
