I don't see why not.
It's not as though they're going to miss it.
Not quite sure of the number of billionaires and millionaires in the world today, but if we were to remove half their money from them and hand it out to the poorest 25%, it probably wouldn't make that much difference to that 25%.
When we living in Nepal, our monthly 'income' was the equivalent of about £350. On top of that we had rent, education and medical costs 'paid for' (well, it was paid for out of the monies we had managed to raise as support (and, where necessary, one person/family's over 100% support would be shared with those who had less than 100% support - usually single people brought in over 100%, whilst families less than 100%). We calculated that our effective monthly income was therefore nearer £700. That didn't allow us to live like royalty, but we were comfortably off.
