Well, that's an interesting elaboration agalkin. I personally agree that one should not simply look for the lowest fees in deciding what fund to purchase. However, if you put two S&P 500 equity index funds in front of me, I'm not going to think more than half a second - give me the one with lower fees. I couldn't care less who the manager is, or any other details - there's nothing else to consider in this case...all other things being relatively the same (for example, a known company running it).
In the case of an index fund, what is it that you're looking at other than fees? I have no issue with the many other factors that come in to play with an actively managed fund, but, with an index fund? It's essentially on auto-pilot - what criteria other than fees are you looking at?
