This isn't actually true. What is true is that there's nothing we can do that is effective, spectacular, and will yield rapid change. But history shows that there's a lot we can do. Even recent history. The people in power now are a specific and stark example of that. Nothing about their rise to power was sudden or accidental, it's the fruit of decades of determined, hard work. And it worked. So look long term. You build the future one brick at a time.

There are lots of ways to fight. Certainly many ways that I suspect you would consider pointless or misguided, such as joining up with like-minded people and agitating, lobbying, etc., or getting involved with the local government, joining the school board, whatever. Also many ways that just aren't your thing. All of that is normal and good.

You don't have to be an activist of any variety in order to stand up. Just living your life as best and honestly as you can, becoming a part of your community in whatever facet you can, and avoiding supporting (financially and otherwise) companies and other organizations that use their wealth and power in ways you disagree with is, honestly, also standing up and fighting. Maybe even the most important way, on the whole.

"Whatever you do in life will be insignificant but it is very important that you do it because you can't know [its real meaning]."

all of that will be captured by the oligarchs and the people will still suffer. we already throw away massive amounts of food to artificially raise profit. basic medicine have their formula frivolously modified to renew patents and keep profits high. considering energy look at america regressing on the daily.
