> Nickle and diming retirement investments does not, in my perspective, contribute qualitatively to society actually, study after study shows that algorithmic traders improve things for "retirement investors". more algo trading leads to lower spreads, which decreases trading costs for long term investors. think about who value investors had to buy from before algo traders. they bought from human market makers who were ridiculous inefficient, and as a result, had to charge huge spreads. these spreads have a material (negative) impact on investment returns for value investors.
