By the way, the point AoC was trying to make when put in context is exactly the argument that the OP was making, which is that people getting rich is OK but it's immoral that people are getting rich and also people are living in extreme poverty, so we should improve the system so people aren't living in extreme poverty.
Where OP differs from AoC is (of course) in his assessment of how we eliminate extreme poverty - AoC is famously advocating a 70% marginal tax rate, while OP suggested some unspecified mix of "technological improvement" and "re-imagining of government" to achieve elimination of poverty. Frankly I think OP is just naive. Maybe he thinks government is literally in the stone age with an army of clerks shuffling paperwork, but I just don't see how eliminating some unnecessary jobs (useful, yes) in government can achieve "medical care for all, affordable education for all, and some amount of income for all" (OP's listed aims).
On top of that, ANY change to government is inherently political. The kind of revolutionary upgrades in government efficiency that OP wants would need to be a major party initiative - which would be opposed by the opposite party, watered down during negotiations, and subjected to compromise by the political process. This is simply a fact about how the world works. We're not an autocracy which means we don't get a visionary Steve Jobs figure who can dictate what the government will do for the next 10 years, and we have to accept both the good and the bad that comes with that.
To think that technology will magically save us from real world problems plaguing real people by "reimagining government" and "cutting unnecessary jobs" is literally wishful thinking. It belongs in a bygone era where tech enthusiasts were sure facebook and google would revolutionize the world by spreading democratic and free speech ideals to every corner of the earth. There aren't easy solutions to every hard problem and OP doesn't seem to appreciate this fact.
