Comet, are you arguing against a progressive tax system? That, almost by its existence, is wealth redistribution if you allow the government to make any type of subsidy or social safety net to any business, individual, or corporation-- say a farm bill, or a tax break for families with children.
No, I am arguing that it is impossible to increase everyone's purchasing power.
Wealth redistribution does not introduce additional wealth into a system, so the increase in a person's purchasing power must be balanced by an equivalent decrease in someone else's purchasing power.
It's not a zero-sum game, because you have players in the game who are actively removing wealth from the economy. By moving the wealth from those players to the players who move wealth into and through the economy, you're changing the amount of functional wealth en toto.
Possession of wealth does not 'remove wealth from the economy'. One does not literally 'sit on a pile of cash'; The money must be re-invested to have any value. When a person puts money into his bank, for example, the money does not exit the economic system. Rather, the bank reinvests the money on the person's behalf.
And no, the statement that "we would be giving money to everyone just for living" does in fact hold true. The fact that you give someone money at one time has zero bearing on when or where that money comes from: you're still giving them money just for living.
It is not 'giving' if the 'gift' was taken from the recipient in the first place.
By definition, wealth redistribution is a zero-sum game. In order for someone to gain wealth, someone else has to lose wealth. Therefore, it is impossible for
everyone to gain wealth.
Concrete example:
There are 4 people in a village, who have, respectively, 2 dollars, 4 dollars, 6 dollars, and 8 dollars.
You take 50% of each villager's wealth, i.e. $1 from villager 1, $2 from villager 2, and so forth, accumulating $10 in total.
You redistribute the $10 evenly, and claim that you have given everyone $2.5 'just for living'.
However, this is how each villager would see it:
Villager 1:
I used to have 2 dollars. Now I have $3.5. I have been given $1.5 just for living!
Villager 2:
I used to have 4 dollars. Now I have $4.5. I have been given $0.5 just for living!
Villager 3:
I used to have 6 dollars. Now I have $5.5. I have been robbed of $0.5 just for living!
Villager 4:
I used to have 8 dollars. Now I have $6.5. I have been robbed of $1.5 just for living!
