On one hand, telling people to just “suck it up” and to simply endure unrelenting injustice while doing absolutely nothing to ameliorate conditions merely telegraphs your privilege.
On the other hand, you still have to survive this life, and sometimes you will be forced to encounter and suffer through grave injustice.
Having purpose—even if it’s utterly delusional—will help get you through dark times. Sometimes the system will kill you anyway, but how you endure the end is still important.
