This is a pretty controversial view of the how market/consumer/style driven economy works.
In one or two places it does over simplify (e.g. with computers, just one small piece added part). However, there are truths in it. Actually, more or less “watch TV -> You sucks -> go and work -> buy things -> watch TV” is part of our lives. It is more less the effect imposed by criticizing eyes driven by styles and trends. I do not know how true are the numbers, but if 50% (they say it 99%) of things are thrown off in 6 months, we have a problem.
