How has leftist thought/theory positively impacted your life?

I think personally the big thing leftist thought has done for me is gave me the mental toolkit to unlearn the idea of “ meritocratic/meritocracy”. We don’t live in a remotely fair world and the idea it is in any sense fair and justice is disproven in just about every leftist text, thinker, speech, figure throughout history. We get some hints about it in religion text (Speaking as a Christian) but we don’t really see how to break it down outside of personal virtue and kindness (which are cool and good but not a scaleable solution).

I really think it super dope that leftist thinking give you the tools to understand and see the Matrix we live. I also really like how it shows you ways of addressing it.

What are things you think leftist thought has improve your life? Big or small?
