Rich people don't actually have that much money, they just have the ability to get money when they need it and most banks and businesses will take multi million dollar IOUs from them because they know that person will be good for it at some point. Most of their "money" is stocks and property. So its not they like they have a massive Scrooge McDuck room where they go swimming in coins, it's just that a bunch of really important things in modern society have their names on it, and nominally take orders from them.
You try to kill them for their wealth, first of all that means they're gonna do anything in their power (which is a lot) to stop you, which means a massive civil war where thousands will die, then if they think that doesn't work, they're gonna start stripping everything of value out of their hard assets so they can leave with as much of their money as possible before you get the chance to kill them, which means all these important things needed for society to function will be gutted once you get your hands on them, and lastly, you'll have to gut them some more to remove all the "petty bourgeoisie" and lesser capitalists (people who aren't millionaires but still benefit from capitalism) that didn't have the money to skip town, otherwise they'll continue practicing capitalism for their own benefit. And the only way to get rid of them is to take all of their stuff and kill them to prevent an inevitable revolt.
And now your industries are all gutted and you're in the process of rounding up and purging every single person who might know how to get things running again. While all that "money" you wanted to redistribute evaporated into the ether and those "greedy capitalists" are living comfortable lives overseas.
