Since 2008, people realized that many systems are entirely broken. This created a large wave of wealth inequality awareness. This is common on both sides of the political spectrum.

At the same time, the left realized that their techniques of debate fail miserably against the monolith of the right, especially after seeing that radicals were rewarded (tea party movement.. all the way to MAGA)

So they are also imitating this pattern.

I know so, because if I dig back enough, I’ll find the comments that predicted this.

The left is radicalizing to match the political capability of republicans.
