मके रस ५ लाख्स अ year

Tell me would you rather make 5 lakhs a year while other people make 3 lakhs a year, or would you rather earn 10 lakhs a year while other people get 20 lakhs a year? Let's assume that the prices of goods and services remain the same. It's funny but it was found that most people select the first option. Why is this so?
