It is understandable to be overwhelmed by the amount of suffering in the world and to be pessimistic about the future, but to say that the pursuit of happiness is immoral is a gross oversimplification of the situation. Happiness is an essential part of human life and our pursuit of it is a natural result of our desire to feel purpose and joy in our lives. To deny ourselves the chance to pursue happiness is to deny our fundamental human nature and deny us the chance to lead meaningful and fulfilling lives.
Furthermore, in many cases, the pursuit of happiness can be a powerful and positive motivator for helping those who are suffering. For example, many charities are created with the intention of alleviating suffering and providing resources to those in need, and the motivation of many of these organizations is the pursuit of personal happiness by making a positive impact in their communities. Thus, the pursuit of happiness can actually lead to a decrease in suffering in the world and should not be seen as immoral.
Lastly, it is important to remember that the pursuit of happiness does not have to come at the expense of others. We can pursue our own goals and dreams, while also being aware of the struggles of those around us, and work to help those in need in whatever way we can. The pursuit of personal happiness should not be seen as a selfish act, but rather an opportunity to live a life of balance and fulfillment. It is wrong to suggest that the pursuit of happiness is immoral.
