they replaced the economy with a freakin cookie clicker
even if you take economics seriously (and you shouldn't), the only thing its own principles actually tell you competition will optimize is commodity prices. do that if you want but if you want literally anything else to work you really need to put it in the hands of humans who have the means and motive to make it work properly, because otherwise what you get is an entire economy that's just amazon
you can design an economy to facilitate the solving of people's material problems, or you can design it to facilitate the accumulation of wealth. economics as it is practiced is not a science but a body of propaganda whose aim is to convince the general public that these two design goals are not manifestly at odds with one another.
