Should NEVER be jealous of the rich and successful. Rich and successful people have to make many sacrifices and detours to get where they are today. While the average people complain as to why he/she did not achieve a certain level of success, rich and successful people PUT IN TIME to achieve their status. They often have to forego temporary fun and games to achieve long-term goals. They also had to stint socioeconomically to achieve financial success.
Many people envy the rich and successful because they want the lifestyle but refuse and/or are unwillingly to put the needed sacrifices to achieve such goals. Look how overachieving people are critiqued and derided in this society. In order to achieve phenomenal success, one must be willing to delay gratification and put in A LOT of sacrifices which only a VERY FEW people are willing to do.
