Why aren't we talking about what will happen when everything is automated?

In order to maximize profits we have to automate. This will no doubt lead to massive amounts of unemployment with too little taxpayers to shoulder the burden of welfare for those that cannot work. Our underemployment/unemployment numbers are around 30% already. As we continue to automate this figure will get higher. Why do we never hear about this in media or politics? The "conspiracy theorists" wont even touch this one probably because it isn't a matter of conspiracy. It's just what's happening. So what's up? Why aren't we talking about this? How high will unemployment and poverty have to get before we start talking about this? 40% under/unemployment? 50%? 60%?
