Higher Income, means that they are financially better off = More money. Hope this helps.

and you can post several questions for just one question , then you will have enough space to illustrate your bigggggg question. italki donlt mind how many questions you post here. lol

choice which makes you feel happier is the wiser choice. we live for life not for money. money enough is enough. lol ·！ don't be too greedy or working too hard for money. thatis dont make money at the risk of your happiness and heath . that is my opinion. thaks.

This is the short version of my question, italki too greatly limited my initial question.
