That’s true for people who do these things without an ideologically underpinning.
There is no such thing as a revolution with an ideological underpinning - Anarc essentially says as much in the video, and, for once, I agree with him.
It is the groups that attempt to hijack the revolution that bring the ideology.
even if it appears to have material benefits.
The left has absolutely failed to come up with an effective way to deal with liberal counter-insurgency even when said counter-insurgency comes with absolutely zero material benefit to the working class - as the (so-called) "Democratic Party" is demonstrating right now in the US - so I'm not exactly sure how explaining anything to the working class is going to change that (which the left has been doing since forever - with rather disappointing results).
I.e. it’s better to be in a union, even if the wages seem to be increasing on their own. It’s better to do a co-operative over a small business etc.
This is all fine and good - until the union (inevitably) gets hijacked by corporate interests and the co-ops are (inevitably) crushed by oligarchic business practices.
And as the system collapses from its own contradictions,
I don't see any real signs of collapse. You can argue that the liberal consensus is in crisis, but, then again, the times when the liberal consensus wasn't in crisis is few and far in between. It has proven extremely... adaptable.
