"Stoics believed that everything in the universe is already perfect and that things that seem bad or unjust are secretly good underneath. The philosophy is handy if you already believe that the rich are meant to be rich and the poor meant to be poor."

But here are some of the things Seneca, one of the greatest of Stoics, said on the matter of wealth:

"Would you rather have much, or enough? He who has much desires more - a proof that he has not yet acquired enough; but he who has enough has attained that which never fell to the rich man's lot - a stopping-point."

"Money never made a man rich; on the contrary, it always smites men with a greater craving for itself."

"we must spurn wealth: wealth is the diploma of slavery"

"Why of your own accord postpone your real life to the distant future? Shall you wait for some interest to fall due, or for some income on your merchandise, or for a place in the will of some wealthy old man, when you can be rich here and now. Wisdom offers wealth in ready money, and pays it over to those in whose eyes she has made wealth superfluous."

"It is not the man who has too little, but the man who craves more, that is poor."

"What does it matter how much a man has laid up in his safe, or in his warehouse, how large are his flocks and how fat his dividends, if he covets his neighbour's property, and reckons, not his past gains, but his hopes of gains to come? Do you ask what is the proper limit to wealth? It is, first, to have what is necessary, and, second, to have what is enough."

Quoting Epicurus:

"Whoever does not regard what he has as most ample wealth, is unhappy, though he be master of the whole world."
