Do you think that income inequality and capitalism may be some of the causes for mass shootings?

I was answering another question here on gag earlier and it occurred to me the things have really changed since I was younger. People could actually work and provide for their families and buy homes with one income. Capitalism was present but restrained an income inequality existed but not to nearly the extent it does today. I believe that because of these things, both of which have changed radically for the worse that many people may be exceedingly angry and not know what to do with that anger. I tentatively believe that these things may be causative relative to the rate of mass shootings, which are now greater than one per day statistically. What do you think? Does income inequality and predatory capitalism and the general state of the economy and make people so angry that they go out and kill others? Or is it something else?

Perhaps less expectation of fairness from the government? I'm just thinking out loud a little bit here is I'm very tired, but at least in the US there's always this expectation that people will be treated with fairness and equity and perhaps for a while to some extent in the 50s and 60s. That was true but then it began to go away and instead we got billionaires. Maybe disappointment is the missing ingredient in this equation?
