Yes, I believe that Jesus will return but not return to establish an earthly kingdom. Jesus will return the Kingdom of Heaven and call the believers, the living and the righteous dead, to join him in Heaven, when this happens, all that will be left of earth is crime, despair, famine, and fear. At least that's what the Catholic Church tells me I believe. Personally, I focus more on living day-to-day and providing the best for me and my family. If and when Jesus does return all earthly concerns will mean nothing.
