The reason is clear. While there is distraction, the real issues are unaddressed and they can keep putting their hands in your pocket when you aren't looking.
Also, excessive pseudo-socialism is a great tool to drive down wages and have the whole world compete against each other. Locust capitalism.
Also, I see your account was created an hour ago.
As for the pseudo-socialism part, I have no idea what it could mean either.
Example: The US healthcare system. The financing is through socialist policies (Medicare, state assistance, regulatory requirements/incentives for employer-provided insurance), but the system itself if thoroughly corrupt and inefficient.
Example: "Affordable housing" subsidies/requirements. Instead of actually addressing high housing costs in general, set aside an inadequate amount of substandard housing with burdensome hoops to jump through to get it and call that a solution when it isn't.
Example: Environmental rules that apply to where a product is manufactured but not where it's sold, so that instead of eliminating pollution, manufacturing jobs move to countries that allow pollution.
The half measures are the worst of both worlds. You get the inefficiency, incompetence and unaccountability of central planning and the externalities, corruption and high prices of market failures.
Thats just socialism.
The definition of socialism is social ownership of the methods implemented. In all cases above, the public at large owns the cost (and benefits) of the methods implemented: Medicare, Medicaid, affordable housing etc. We all pay for them, full stop.
Just because some of the programs have worse outcomes than elsewhere in the world, doesnt make them "less" socialist policies.
Socialism is meant to be a counter-force to unrestricted capitalism. America lacks this counter-force. Instead, America has a (so called) Left that is afraid of being branded "socialist". Because they cannot embrace genuine socialist policies for fear of upsetting their very wealthy and powerful patrons, they are trying to win votes by appealing to people's pathological tendency to form rival tribal groups. This is quite the irony, considering that socialism's original rallying cry was the (inherently trans-tribal, trans-national)"Workers of the World, UNITE".
True socialism looks for opportunity in horizontal social partitions (the social classes), whereas nationalism looks for opportunity in vertical social partitions (ethno-linguistic and religious segregations). This is why nationalism is the capitalist class's preferred evil -- it directs the dissatisfaction and anger of the lower classes against each other, away from the wealthy. Both the American Left and American Right are focusing on the vertical (tribal) partitions -- it's just that the Left is very polite and composed about it.
This is what (I believe) the GP tried to imply with the term "pseudo socialism".
