Would just like to pop in here and say that terms like “millionaires” and “billionaires” typically refer to net worth/wealth, not income. This is why Jeff Bezos was able to claim some of the federal COVID aide because, despite being a multi-billionaire, his income in that year was below the threshold (I think it was sub-$100k) as income from investments didn’t qualify under the structure of the plan.
While I don’t necessarily disagree with the sentiment of people whose net worths are upwards of a million being able to claim unemployment, actually calculating net worth is extremely difficult to do, especially among the wealthy. That would put an unreasonable burden on the unemployment benefit system that would probably end up costing more in administrative costs than the money saved by not including to the ultra-wealthy in the benefit. Preventing the latter is the main benefit of universal programs
