Why are successful people so often criticized by others?

My salary isn't very high, I earn an average salary, but I save money every month. Even if it's just a small amount, I always put aside money each month. This way I've traveled to many countries, and I share the countries I visit on Instagram. One of my videos went viral on the Explore page, and many people are saying things like, "Is traveling to visa-free countries considered country travel?" and are attacking me, saying I'm paying with my dad's money, with comments like, "Which man paid for it?" But I save up money myself and try to find the cheapest plane tickets when I travel around the country, I even eat street food. Sometimes I get by on just one meal a day, but people criticize and comment without seeing that.

Why has it become so difficult to empathize? For example, I see a man, well-dressed and happy, but sometimes I wonder what hardships he's faced, because beneath every smile lies pain.
