It’s harder to advocate for destroying things one possesses.
If we want to end Capitalism, not being invested in it is probably more helpful than not.
That said, I have met a fair few people that would fall under the label of “Leftist” that have had small businesses. Although not the hyper-radical left.
About 70 hours, at that time in my life it was normal for me to go 24 hours or so without sleep because I was addicted to WoW.
That time I realised I’d hit 30 and decided to see how long I could go without sleep.
At somewhere after 60 hours I began hallucinating and became convinced that there were elephants inside the walls making them deform.
That was the sign I needed to go to sleep, and I slept for almost 20 hours straight.
