I always wondered, is it actually possible for us to ever assume that we can achieve better unemployment rates or is there a practical minimum which we can never get below again. If you think about it, in a world without technology, the money we spend has to go to someone in the economy. However, since we know have artificial workforce in play, we effectively pay less, which means that we in consequence pay out less than we receive. So eitheir we all get paid less (yay communism), or some people just naturally have to be unemployed (yay income inequality).
