Assuming AI does replace most jobs, what makes you think the government, or the AI trillionaires, will be motivated to share what they own with the now massive jobless?

I hear a lot of people talking about how great AGI will be, but chances are, if AGI pans out like you think it will, you’ll be out of a job. Most conceptions of AGI are artificial intelligence that is greater than human intelligence and can outperform humans in most respects, and is generally cheaper to use than human labor. So, hypothetically, when AGI replaces your job and you have no source of income, what will motivate the people with resources to pay your welfare? There are a lot of you, so it won’t be cheap, even with an AGI-enhanced infrastructure - so I’m curious, what will make the AI-owners willing to give up a massive percentage of their wealth, especially when they’re competing with each other?
