sometimes the income bsomebody earns can be used to classify people in three social status i.e high earners for rich, middle earners for middle class and poor for those who earn even less than a dollar daily. as you know consumer income is one the demand. thus those who earners highly like buying expensive products or service unlike low earners. like low earners can take a public transport like train while rich one can an expensive car for both going to same destination.
