There are very wealthy people that exist who are horrible people, but owning wealth does not make you inherently evil or parasitic, and on the same note, being poor does not mean you are lazy either.
I second that, and actually I believe it's not mandatory that a rich person touches the lives of others in society, don't get me wrong, morally it's right that if you're so wealthy you should impact the life of others as it would cost you little or nothing, but not doing so doesn't make you a horrible person, at least that's how I see it, except such Individual is part of the government as I feel it's the duty of the government to try its possible best to make sure it's citizens lead a very good and comfortable life.
I also believe that being poor doesn't automatically translate into the ideology that the person is lazy, I absolutely agree with you on that, there are quite a lot of other factors that can play a part in a person being poor, and mind you that there are hard-working people that aren't rich, there's just no straightforward way to decide these sort of things.
