Why do hedge fund manager chase returns? Should they not forecast markets like a true quant based around math?

I was watching Bloomberg with hedge fund manager complaining how they are getting crushed with lack of returns. Seriously, why do they chase the market? All they said was that carry forward trades were their only profitable strategy. It seems low volatility is crushing them. If they were smart, they could forecast the markets like true quants.. It seem these fat cat lazy bozos will no longer be able to validate their place in this fast changing financial market. HFT shops are killing everyone so adapt. Just a thought
