The truth is, we're all to blame. We go about sharing images of branded clothes, watches, makeup, phones and cars, in that order, to manifest status symbol which shouldn't be the case as material worth is nugatory. Don't get me wrong, there's absolutely nothing wrong with treating yourself or posting your pricy possessions online, however, there's a fine line between pampering yourself and being appreciative and bragging about your luxuries to others.
My point is, not everyone is as fortunate as you are, so by showing off, not only are you presenting yourself as a narcissistic, selfish and egotistical savage , you are also making others feel resentful. So, either way, you lose. Trust me when I say that you'll be doing yourself a favour by cutting out this egocentric habit of yours. If this doesn't apply to you... then erm soz m8.
