Your logic is flawed and you are being foolish
1 - If you don't need to put any money in, but can take money out, then that is not a ponzi scheme. (In fact I would encourage you to alert me if you can find another system where you can receive money for your work without investing).
2 - You are being blinded by jealousy. If you were the one receiving $1,500 for your comment, you would be singing another tune. (I will bet you $100 dollars that if someone were to offer you $1,000 dollars for your work you would take it without question as to whether other may be jealous).
3 - I looked at your wallet and you have made money here. Unless you are a celebrity or youtube sensation, I am guessing this is more than you have made on any other social media site combined.
4 - As a token of good faith I will instead of flagging your comment, reward you with 1 steem dollar. Why would I do this? Because I wish you to stay and see that steemit is more than just money. A community that shares money together in a positive way is a great thing and I am going to share with you even though you do not deserve it.
I will await your response. In fact instead of 1 I will give you 3 steem . Check your wallet, since the blockchain transparency will prove I am not lying
