PoS doesn't require any work.. PoW does. There is a massive difference there.
Ok, but your other point was that people who have lot of money are able to dictate all the rules with PoS. This seems to be the case with BCH SV. These are your words, read back.
WIth POW your money is used up continuously, with POS your money earns you more at a rate proportional to the size of your initial investment/size of network.
There is a difference in just having lot of money & using this to have power to make decisions, This is PoS based system. When you have to do the work instead, its not the same thing.
