1) 'Means of production' do not arbitrarily further inequality. The Industrial Revolution, which we may very well be still living through (ask a historian in 500 years ...) smashed the old class systems and enabled standards of living unheard of before.
2) 'Tech' is in its infancy, the measured surpluses i.e profits are going into the hands of the 0.1% but consumer surpluses are huge. The value of the things we can buy today are immensely greater than before. I play a free video game that has provided me with countless hours of entertainment. From 'older tech': I get this amazing stuff called 'electricity' out of my walls and literally fresh water (hot and cold!) for literally pennies - this is revolutionary. You can live better than a Roman Emperor by shopping exclusively at Walmart.
3) A few billion people have come out of 'extreme poverty' in the last 40 years, as basic material prosperity reaches every corner of the planet. Computing has been part of that. Despite our own ugly inequality, and all the ugly externalities (pollution etc.) - we shouldn't denigrate this fact: having 'a roof, food, the ability to communicate with people at a distance, basic medicine/healthcare, basic rule of law' ... this is heaven compared to any situation their ancestors would have lived in.
Computing is as worthwhile as we want to make it, much like most other things.
