Getting quick execution is nice. It's part of getting a good price - the price I want at the time. Retail investors would normally go to the back of the line, do you think human brokers and market makers are fair?

I execute fairly quick trading strategies, I hold a stock from a day to a week, being able to sell at the peak of an up day or unload shares when the market is just beginning to move against me, as opposed to minutes or hours later is everything.

And as another poster said, most of what HFT is, is market making... (Even traditional MMs made their money on arbitrage)
