"Other people's money" gained how? Hard work? Undoubtedly, unless inherited then it's other people's hard work, slaves included. Through other people's hard work? Also undoubtedly and always with less monetary reward or incentive.
There's a notion that if 'other people's money' is distributed more evenly people will become lazy "why bother working hard when I can have money for free"...if only so freely claimed.
On the other capitalist's hand, people are incentivized to work harder by removing support and creating an image of more money being attractive and worth working all hours of the day until enough is 'earned' to employ others to work for us so we no longer have to work so hard blardy blardy blar.
Theories only work until they run out of other people's patience. Squeeze people at both ends and we eventually explode or implode depending on how we've been conditioned to button up that stiff upper lip or not.
So, other people's money? Aside from all money belonging to the banks, an IOU, it's money, not wealth, money that changes in value daily and depending on which system is in play either trickles up or down amassing un petit petit petit peu in the middle but always mostly up, nearly all in fact, and always very much lessly down. (that's gotta tickle those grammar nerves. 😬 )
Either way, the budget of a country does not work the same as a household budget. That wealth of unknowledge needs to get out of circulation..a Thatcherism that holds no value other than to debunk the left who's idea of socialism also includes capitalism so not so commy as one might be led to understand. No, money spent out of the household purse is gone once spent, right? Ever to be regretted in haste. Money spent out of the country's purse ie all our money and once spent and borrowed (borrowing produces more money), circulates, gains in value as inflation is also decreased (?), so better spent in the public interest rather that "other person's" private stash often offshored whilst said other person gets his or her sense of value by rubbing all our money into their millions worth of extraordinarily clean white yachts and claiming how so very much more deserving he or she sitting high on their gleaming tower of power is because he or she was incentivized to work harder whilst not having his or her safety net removed (not including the small business persons who had the health, ability and confidence to start from nearly nothing..that's another story but one which still very much involves other people's hard work somewhere along the line), n'est-ce pas? 🤔
Who knew the economy could be so complicated, eh! 😜
