What income bracket do you believe has the highest appreciation for life and personal joys in their existence?

My parents started out poor when we first came to Canada cause they had no Canadian job references and their friends were just as poor and unaffiliated as themselves in the job market. Back then, the thought of eating chicken nuggets at McDonald's could make me extremely happy for 3-4 months. Now at my current age, not even lobster boosts my mood that much. I also enjoyed vacations more when my parents made less money and I liked parks and material things more too. Now I will even say no to vacations when they are free cause family is offering to pay for it. I rejected a free trip to Las Vegas this year and now I've rejected a free trip to Switzerland too.
