A country that only produces essential items (food, shelter) for its population is a very poor country.
Almost by definition, a wealthy country predominantly produces and consumes non-essential goods and services.
It gets really difficult to argue which non-essential goods are worthwhile. Is the art on the wall worth more than the stone lintel? Is it good art? Is it a second hand lintel?
It's always been like this though. In the end, there's no reason for humans to have ever made most of the things we have over the millenia other than because we can and did. Once we had food and shelter and all these things pretty much taken care of, everythong else after was pretty much just for the fuck of it and we've always been at odds with the world and destroyed and altered our environments. The scale has just kept increasing to the point where there are massive global industries devoted to this.
At the same time, humanity still follows our basic survival insticts. We still have that inner subconcious mentality of scarcity when it comes to essentials. So it ends up being treated the same way in our economy as luxury goods and you end up in this situation where people are trading non-essential things for essential things.
Though again, they remove mountains for this, the shop produces a bunch of toxic, fish killing dust and sediment every day that's slowly killing me and my coworkers and destroying the planet.
But my main point was, the things I create every day are not essential. They are luxury items. Many of the other jobs i've had were also along the same line.
Not that they don't make people happy or improve their lives I suppose,(though the people that got soapstone in their kitchen recently are in for a some trouble the first time they drop something on it or spill something acidic on it.) But, in the end, it's definitely not essential and detrimental to the world as a whole in many ways.
