Of course, the more active a fund is, the farther it gets from zero sum, but it would never be fully zero sum.
Additionally, financial services overall are far from zero sum. There is a great deal of efficiency and market lubrication created by financial services and if you exclude the high frequency traders, you leave a huge majority that is still quite beneficial to people on both sides of the transaction.
Once again, that depends on the trade, short term trades don't make their money from dividends, but from timing the market.

Beside the point, plenty of them are zero-sum-never said they were all zero-sum; that exception exist doesn't change the point that zero-sum vs non-zero-sum is a false dichotomy, the real world is both zero-sum and non-zero-sum, depending on the way the wealth is being generated. It's tiresome watching people continually repeat the incorrect mantra that wealth isn't a zero-sum game when quite often, it is.
