I’d disagree with that. I see that the gains we’ve made in quality of life are often the result of literally fighting for change. The systems we live under are the result of incremental change over a long time and should be questioned and resisted when our ability to live a full human life is threatened. The systems we built 10 years ago are unlikely to be perfect, nevermind 200 years ago. There’s a reason the US constitution has the amendment process. It is a living document we are ment to change to address the problems we face. Knowing what it took to get the changes in the past let us weigh whether the changes are worth it and the ruling class knowing we know our history means they know what’s on the table.
If you choose to call living a life with a degree of awareness and the ability to be more than a profit generator far left so be it. However, I’m very fond of not working 7 days a week, 12 hours a day, and dying from preventable illness due to gutted safety standards.
