In fact, almost all of the consumption is driven partly or mostly by wants or desires, way beyond needs. Especially in the developed economies, it's actually easy to calculate the monthly consumption driven purely by needs, such as water, gas, electricity, public transport and health care. Almost all the rest is heavily influenced by wants or desires.
For food almost everyone spends way more than required to keep the body running healthily, and in various types of cuisine to keep us from getting bored. In terms of housing it's very common that people stretch their budget to go for an ideal apartment, either in rentals or especially in purchases.
And almost everything we buy on Amazon or in Walmart fit the wants or desires profiles better than needs: books, music, movies, consumer electronics, gardening, beauty, toys, sports, etc. In fact, take a look at the Amazon directory page and one would be hard pressed to pick out a product/service category that is truly "needed".
