What are the logistics of a class revolution?

I’m not a communist, i’m not an anything ist really. I don’t know much about anything to be an ist. But i was watching a reel (i forget about what) and a comment stated that the left focus on too many issues at once or periodically and then discard them after a while to focus on the new urgent issue. But I’m wondering how left wingers would enact any collective change any way other than taking down the class which is allowing or is behind wealth disparity, wars, child and human trafficking (especially those in the files)? Where would the children stay of mothers? Do they just storm in like during the french revolution? Is everyone too comfortable to enact any real change? Is it futile as power dynamics cycle with time?

lmkkk thank you in advance.
