I don't understand what a product manager does, from the video they seem to be reading information-output on a computer screen and then they input information back into the computer based on that. Some capitalists are probably trying to use that information to train an artificial neural network, and replace them with a bot.
On the other side of that equation is that if all the people work in a digital office, you don't need capitalist owners anymore. Because there is no more capital involved.
The Bullshit jobs might be about ideological control.
>you can have relatively productive economies under laissez-faire capitalism, but 2022 America doesn't fit this category at all.
No you are extremely wrong about that. You have been tricked by ruling ideology.
Capitalism does not prefer productive labor if you let capitalists do as they please, under the neo-liberal doctrine, productive labour = everything in the private sector. unproductive labour = everything in the public sector, regardless what the activity is.
The way Marxists qualify productive labor, as something that generates persistent wealth that can be accumulated by society is not how capitalists see it. The big bourgeoisie want this shit economy, they want to have a big unproductive service sector that tends to their needs, they want luxuries for them self, they want too much military spending to attack their rivals, and from their perspective the current system isn't broken, they get what they want from it. They don't care that, luxury yachts/cars/mansions are unproductive, that financial services hiding their assets from taxes is unproductive, that bloated corporate bureaucracy for controlling workers is unproductive, that data surveillance is unproductive, that blowing up countries or overthrowing governments is unproductive, that ideological enforcement of ruling ideology is unproductive. All that stuff benefits their class interests, if you let capitalist do as they please ( laissez fair ,if you prefer French ), this is what you get.
If you want more work directed at productive tasks you could go for a soviet style planned economy, cybernetic socialism, social democracy or the chinese model. All these models divert more labor power to the productive sector, either by removing the capitalist class altogether or by controlling them via the state and organized labor.
here is a short 10min video about un/productive labor that explains it much better than i did
