The resources exist, it's just a matter of allocating them properly. We have lumber and concrete to build houses. We have fertilizer and land and trucks to grow and ship food. And apparently all of this will be immensely cheaper (practically free) within a decade thanks to robotics and AI (according to the trillionaire half this place worships.)

With that said I doubt that reallocation will happen in any meaningful way, and as the elites eliminate more people from the economy we'll descend further into violence and chaos. If the parasite class was generous, they wouldn't be parasites.
