Because your job doesn't care about you. American culture has been gaslighting the general public for decades that “if you work hard enough you can live and achieve the American dream” when in reality all that has happened is that we've been screwed. The American Dream died once Nixon got in office, and ever since then we've tried to strive for a level of greatness in vain. The people you saw that are successful were either a) lucky or b) old enough to live in an era where the possibility of the American Dream was still alive. Instead, focus on what matters most like your family, hobbies, and loved ones. Stop buying those expensive things for status it it doesn't need to be replaced; go travel.
