Why would they feel differently? This makes no sense to me. Wealth envy is wealth envy, whether you are millionaire envious of a billionaire or a homeless person envious of someone living in government housing. There are no parameters to this, you either have the mindset that some people have more than they deserve or you believe people make their own way and deserve the fruits of their labor.
We have equal access to education in this country, it's been the law of the land for decades. We have laws which punish parents if they don't send their kids to school, it's mandatory that kids up to age 16 remain in school. There is no disadvantage when it comes to educational opportunity, we all have the same access to the same resources. People who are wealthy, for the most part, weren't just handed their fortunes... that is sometimes the case, but for the most part, it's not. For the most part, wealthy people started out just like you and I, and the poor person on the bus, and they worked hard to achieve and accomplish their goals, they had the ambition and drive to succeed, and they didn't turn themselves into 'victims' who were incapable of greatness, they kept believing in themselves and the dream, and realized it.
Now you want to take these people and say, they don't deserve to keep what they worked so hard to attain, because here are these less motivated people who are still riding the bus, and it's not fair they don't have all the wealth of the person who was driven to success. You want to pretend the cards were somehow stacked against them, they didn't have the same luck in life, as if wealth is acquired by sheer luck and fortune.
Instead of your poor person riding the bus through the rich neighborhood seething with bitterness and feeling sorry for themselves, perhaps they should be pondering what those wealthy people did to get to where they are? Was it more emphasis on school and education? Did they avoid getting married and having kids? Did they work part time jobs at night for a while? How did they get to where they are? But you see... that requires "self-evaluation" and coming to terms with the poor decisions you've made, and realizing YOU are the problem, not the rich person. So it's best to just keep seeing yourself as a victim, and the wealthy person as undeserving. This way, you can continue to live in denial, blame others for your troubles, and never have to accept responsibility for your life.
