text: I think it is because People tend to become accustomed to a particular style of living, regardless of their level of income.  For those who are making less than that same level, they are comparing two different frames of reference.  It is easier for others to see it as 'unappreciated' while the person with that level of income may just see it as 'commonplace'.\n\nIt is almost like moving from a minimum-wage paying job to one that may pay 25k - 30k a year.  You will find yourself most likely spending your money to buy more items that you like, while those making minimum wage will have less.  You may become accustomed to those things and may not be as occupied with them, while others do not have them.  This may soon lead them to think that you do not appreciate the things that you have.\n\nPeople do tend to appreciate the things that they worked hard to attain, even if their attitude may suggest that they do not.  It is just that their lifestyle is in a different frame of reference.
