As just mentioned, present hedonists live and act in the moment, frequently with little to no thought of the future, or the consequences of their actions. Most children and teenagers are present hedonists. Each day, they build on past experiences, but their concept of the future is still under development. People suffering from arrested emotional development, usually caused by a childhood trauma, are also present hedonists. Without therapy, the ability to mature emotionally beyond the age of trauma is difficult to impossible. When they reach adulthood, they may be able to hide their lack of emotional maturity for periods, but then, when in a stressful situation, they revert to behaving the emotional age they were when they were first traumatized. Depending on the degree to which the childhood trauma affected the person suffering from arrested emotional development, they may find that, over time, their present-hedonistic time perspective has morphed into extreme present hedonism.
Without proper individual assessment, we can only make a best guess as to whether Donald Trump suffers from arrested emotional development, which may or may not be a factor in his extreme present hedonism. Yet, with access to the extensive amount of print and video media exposing his bullying behavior, his immature remarks about sex, and his childlike need for constant attention, we can speculate that the traumatizing event was when he was sent away to military school at the age of thirteen. According to one of his biographers, Michael D’Antonio, Trump “was essentially banished from the family home. He hadn’t known anything but living with his family in a luxurious setting, and all of a sudden he’s sent away” (Schwartzman and Miller 2016). This would help explain his pubescent default setting when confronted by others.
