1st of all, remember that if it weren't for other people, companies wouldn't be able to hoard large sums of money. If it weren't for certain governmental protections, this wouldn't be possible either. If it weren't for certain services this wouldn't be possible. And most of all, if it weren't for the use of artificial wealth (paper money, digital money, gold, silver, etc.) such great hoarding wouldn't be possible. Before the use of such technology, people couldn't hoard wealth in the same way. If one were to hoard a barn full of apples that they were somehow able to pluck from the trees before anyone else could, those apples would go bad and all their effort to gain wealth would have been for not. So just remember, massive wealth accumulation is not really a "natural" phenomena. Government helps keep things natural, so to speak.
