I read this as Democrats adjusting their perspective in line with the adjusting reality of the world around them: obviously corporations are making mroe and more and more and more money than they were 25 years ago, especially at the top. Why wouldn't perspective on that fact change? It is only reasonable, right?
We even hear from righties all the time that "racism is far worse than it was before Obama was president!" So ah, why should liberals not be able to see that changing tide as well? ...admittedly, it's strange to see a poll where conservatives move against some of their more vocal arguments, but whatever. I guess that isn't really new. likewise with the first point: with wealth concentrating more and more and more at the tippy top, what kind of reasonable person thinks that poor people could ever experience anything like "freeloading" with the pittance that is available, and is factually claimed in considerably small numbers, that is welfare?
I think Jordan Peterson describes this in a fundamentally articulate way, so I will try to paraphrase.
Biological life must move forward to survive. It must seek resources and the proper conditions to survive. The result is that when looked at intellectually, this can be called having an aim, the aim to optimally survive. To have an aim or a goal means to create value, to create a hierarchy of meaning where the good can be categorized and described. As soon as any system of value is established, of any kind really, a hierarchy of competence is also created simultaneously. Some people will be better at whatever the value system is than others are. The result is inequality.
Since order is stasis, inequality will inevitably increase due to the fact that the system will be gamed by people seeking advantages they haven't the real competence to achieve. This is where the left becomes vital to the survival of systems. The inequality must be constantly remedied and checked. We need both order and the chaos of openness and creativity, new avenues of adaption because life can't stand still. There must be a balance between the left and the right and neither can exist without the tension provided by the other. This is why both conservative or liberal dominence is dangerous. We need to adapt to changing conditions without falling into total chaos. The way to move forward is via dialog not ideological warfare.
The author of the original link, in my opinion, doesn't see the vital role liberals must play in protecting those who are ill equipped to be competent in the system nor sees how out of whack it has become.
Here is an interesting story Peterson tells:
The army became interested in how to find competent soldiers and has a law or a rule now that they will not accept into service anybody with an IQ below, I think 85 or 83, not sure which because they discovered by testing that people below that IQ could not master any skills needed to be a decent soldier. That is 10% of the population the Army says are unable to benefit from training to be proficient in any army job. What are we to do with such people particularly since there is zero correlation between IQ and being a decent person. Are the data wrong?
