Because the average person doesn't have any real time to think deeply about politics.

Because the economic elites have engineered it that way.

They flooded the workplace with double the workers (both men and women), thereby depressing wages and forcing both parents to become wage earners to survive. Then, with both parents working outside the house, childcare and chores sucked up all available free time, and even more household costs went towards outside help (daycares, etc.).

Then they began a tradition of kicking children out of the house when they became adults, thereby putting strain on infrastructure and increasing the demand for housing.

Then they began a push for higher education, thereby saddling young adults with ridiculous amounts of debt at the point of their lives when they could least afford to shoulder said debt.

All this makes us extremely time poor and resource poor, such that we cannot afford the head space to consider anything beyond where we put the next step or two that we make. As a society, the common man becomes far too busy just treading water to be concerned about in which direction they should swim.

As such, most people take massive amounts of cognitive shortcuts, relying far too much on things spoon-fed to them from the very news sources that should be unbiased and impartial, but which are nearly always owned by the Parasite Class, which favour deeply regressive conservative policies that benefit only themselves at the expense of the common person.

And most people don’t think deeply not because they cannot be bothered to think for themselves, but rather because they have far too much on their plate to afford to do so. They quite literally would mentally burn out if they were to do so.
