Given his lifetime performance he is likely on the side of the capitalist status-quo as well as of his bank. In that capacity he is smart enough to not collapse into self-delusion all the time. So now he looks around and considers that what he sees supports the view that things are not in great shape in the US politically, economically or culturally and that the Trump regime - however much it helps big banks - is likely to roil US society further and perhaps in ways that could threaten Dimon's bank and the status-quo capitalism he so loves. So he says something - vague, general, but reflecting is uneasiness about the times we are living through.
My simplest reaction is "Duh!"
