Yes, they deserve, like everyone else.
But they rely too much of their happiness on what others say/do.
They compare too much with what others have that they don't, so that they forgot to look at what kind of fortune they have in their own hand.
They dwell deeply on what others wouldn't give to them, instead of using what they have to create a life that they root their happiness upon.
(Or they just desperately need more money than they have already to be happy?)
Their hearts were dominated by the past regrets and by resentment, so they can't feel true happiness.
