I think you are right in a way. If we are not strict with the definition of a Ponzi scheme, a lot of things can be classified as Ponzi. 

People who call Steem a Ponzi are in fact implying that stocks and other crypto-currencies (including Bitcoin) are also Ponzi. Which obviously does not make sense.

When you buy a stock in company (or a Bitcoin token), you do it because you assume that in the future there will be someone else who will buy it from you at a higher price. So yes, the financial outcome of your current investment depends on someone else making a new investment in the future. If we treat this as a valid symptom of a Ponzi scheme (which is wrong!) then yes, most financial instruments (Steem included) are Ponzi schemes.

@gmalhotra " Where does the money come from? Obviously from STEEM and Steem Power holders"
please again give little more attention to the above sentence which @clayop written in his post and most easy sentence at the end in conclusion is that Steemit platform that rewards content creators and curators through redistribution.
So in Steemit you only get your earning through contents rewards,curation rewards  in distribution and redistribution.

In a Ponzi, person B still has a claim on the money, despite it having been fraudulently distributed to A. 

When company earns profits from customers (B) and then gives those profits to shareholders (A), B no longer has any claim on the money.

That is the difference.

Now it is possible that _some_ companies are indeed Ponzies, where earnings are nonexistent or overstated, and money from other investors is misrepresented as earnings, but that is not the general case.

Definitely am not jealous.  I wrote this: https://steemit.com/ponzi/@gmalhotra/ponzi-vs-stocks-vs-bitcoin-vs-steem-my-opinions

 Its a full explanation of my views... If you care to read it.  Just trying to create a healthy dialogue... No jealousy :)
