Well, now that you mention it, I think it is totally fair to take a critical view of the way we allocate the rewards for a successful enterprise. There's no natural law at play here. We live in a system that deliberately rewards founders and financiers over the other pieces of the puzzle.
The creator was one of the early miners and benefited from that, but whoever Satoshi was, he/she did NOT reserve a large number of bitcoins. (This HAS happened with certain other alt-coins.)
Well, he wouldn't have gotten more than any other early adopter. And nobody accuses them of being scammers - just taking a heck of a gamble and it paying off.
Edit: Apologies, I did more research after posting this comment. Apparently Satoshi did mine quite a lot in the early days, but the addresses he used are well-known (one of the advantages of a public ledger - go to blockchain.info and look at any block with an index less than 20,000), and if anyone tried to spend them, it would be in the news.
