I think the products/services the market provides mostly enhance our lives. Society works better than than our cynicism would imply, and when you zoom out over a span of a couple centuries, or even 40 years, that becomes apparent.
Of course there are many cases where the consumer is underinformed, and harmed by what the market urges them to buy, and these need to be addressed.
On the other hand, we are potentially now closer to our doom than ever before. If we look at all the things, that _in the short term_ improve our lives, but _in the long run_ might seriously impact future generations, then I am no longer so sure about that statement. Zooming out is fine, but not only looking at the past, but also what the future seems to hold, is a worthy perspective to take sometimes.
