I think a lot of the time, not all of the time mind, it comes from the parents trying to instill a sense of perspective. For example, when I was growing up, we were poor. Not, I am concerned about my financial security poor, not I may not be able to go to uni or get a new Iphone poor, we were scrounging for shrapnel at the back of the couch to pay the bills before the power was cut, my parents were ( I found out recently) skipping meals because they could afford to feed themselves or us kids, not both. But, as my father is very fond of saying, we always had a roof over our head and we (the kids) always had food on the table. My father, when he was growing up, had none of this, having grown up in a boys home and never owning anything for himself.
My family is well off now, most of us (including myself) have moved out and we are all doing well, but the other day my sister (my older sister btw) started complaining about how my father was canceling her Austar and demanding that she pay for her own internet. SHe gets massively angry whenever someone challanges her view of what she deserves. This leads not only to my father telling her that 'I had it much harder' but 'we all had it much harder' just to try and get her to appriciate how good she has it.
