Interesting for me to hear the perspectives here, that venture capital firms ruined them. I always thought it was simply a case in which GC expanded too much too fast. But I guess the capital firms played a role in that.
VULTURE, not venture. Venture capital is what you get as a startup. "Vulture" capital firms, like Bain and Ares, generally operate on a model of buying distressed companies and, in theory, trying to turn them profitable, usually by cutting costs. In practice, they do not often behave this well, and buy companies, gut them, sell off what pieces they can, and abandon the companies with staggering debt. Toys-R-Us is a good example of this process in action.
I have mixed feelings about GC. There are two that are about equidistant from me, and one is actually quite good. They have a decent selection, keep the stuff in reasonable shape, and while they're not always knowledgeable, they at least try to be helpful, and if they're not busy they're pretty patient.
If GC were to go away completely, then I'm not sure where I'd get to try out gear in person. I'd be happy to shop at mom & pop places, except there aren't any anywhere near me. If GC went away, would someone come in and fill the need? Maybe, but I'm not convinced. I kind of hope they can work through this and stay around.
