I acknowledged your point. I also agree that the individual should focus on what is in their power to exploit. But I think it's also important to recognize and work to fix systemic issues if we value a just system. Both can be true at the same time and I think it's sometimes a mistake of the hustle-porn mentality to focus exclusively on one while ignoring the other.
You choose here to focus on the fact that some people have more angles available to them than others. You call them privilege and believe them to be unjust. If you do that too much, you'll defeat yourself and destroy your own agency.
Maybe you're right, maybe they are unjust, I do have opinions on that sort of thing, I also think the best places to indulge those opinions are at the ballot box and at my desk writing checks to nonprofits. I mean I do screw this up and focus my time/energy/attention on them at inappropriate times. But I know it is a screw-up when I do it. No one is serving the greater good by wasting time.
