You have to have money to make money.

Not true.. You need good credit to have money and make that money make you money. Or ask for a loan from a person instead of a bank.

And isn’t greed a sin? isn’t having billions being greedy? You just hate poor people, don’t you?

Greed is a sin. It is subjective, having billions doesn't automatically make you a greedy person. If you have billions, are you giving to charities?

I'm Muslim so here's this:

The Quran encourages believers to be generous and spend in the way of Allah. Surah Al-Baqarah (2:177) emphasizes the importance of giving: Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah, the Last Day, the Angels, the Book, and the Prophets and gives his wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous.

No, I don't hate poor people. I was born into a lower middle class family and if the world was perfect, all humans would be wealthy and live financially stress free, accessible to any and all resources needed to prosper.
