The rich are the leeches...
They say this a lot but it implies some mechanism by which one thing--presumably wealth--is taken from the poor and transferred to the rich.
The poor aren't paying taxes* so there must be some other mechanism.
I suppose the DUmbasses might grudgingly admit any transfer of money involves the exchange of currency for goods and services but that implies a voluntary activity and that just doesn't comport with the necessary need for anger.
They then shift their complaints to encompass the necessities of life. However, America has the richest poor people in the world and things such as "food insecurity" and homelessness are the exception and often accompanied by extenuating circumstances, i.e. mental illness, substance abuse, etc. or it is short-term (I was once technically homeless for 2 weeks, unable to gain an apartment though I had plenty of money to do so).
It should be noted that if the "rich" charged vexatious amounts of money for life's necessities they would lose customers--and with them, their revenue--and they could not afford to employ minions to make the requisite transactions. In other words: if the rich charged $100 for a loaf of bread no one could afford bread unless the rich also paid their employees $1,000/hour to cover the cost of sustenance and the rest of life's needs. After all, someone has to plant grain, mill, mix, knead, bake, distribute and sell for bread to be brought to market. Certainly the evil rich are too busy cackling over piles of filthy lucre to be engaged in such pedestrian concerns.
However, as we all know the word "necessity" becomes distorted with leftist agitators. Once it can be shown food, shelter and clothing have been satisfied the list grows to education and healthcare et al and from there it becomes transportation and communications on to vacations and entertainment.
And all this to be wrapped in a bow so a to preserve the individual's sense of dignity. After all, it won't do if the Haves are different from the Have-on-someone-else's-dime.
so obviously only a leech would oppose this.
