There are billions of us. We cannot all be capitalists and start our own businesses. Literally 100 years ago American socialists like Olive Johnson were already pointing out how the profit motive from large players has ruined mom and pop shops and made medium businesses almost completely beholden to production and finance monopolies.
What do you think will happen with the increased production from AI? Will the capitalist just allow the masses to compete openly with them?
I doubt it. Most likely more monopolization will occur.
Small business owners are the tip (retail) of the massive whole-sale industrial-production monopolies or they are artisans at best. And the masses are the rest of us, the 95%.
Western suburban mentality always posits that these ills cannot happen, even though they were continuously happening even through out the 20th century (Detroit is just one example).
