The bourgeoisie in my country have pushed the euphemism of "working capital" as something that needs protection from wealth tax. By inseparably connecting capital with jobs, they push the narrative that you cannot tax wealth without removing jobs and consequently hurting the working class. They paid for research groups to prove this connection, but what their research actually showed was that wealth tax creates jobs due to incentivizing keeping profits within the companies they own. The audacity to think owning the means of production is a privilege they should enjoy special treatment to keep is beyond me, but even so, this type of rhetoric keeps gaining ground.
What is the propaganda they are pushing on you, and how can socialist policies prevail if reason loses to made up words changing the narrative?
Domestic work is work on the same level as all other work. Proletariat is probably a better denomination for the class (though I personally use the terms interchangeably) since it is not so much distinguished by all the members of the class having regular jobs, but by them not being part of the class that can make capital gains by exploiting other's work potential. I agree that class solidarity is a huge issue though and I think the idea of attributing not having a regular job to laziness is propaganda with intent of pushing this wedge further.
