Look up crisis theory, the rate of profit tends to fall in capitalist systems. Because each company is driven by competitive self-interest, it is incapable of acting for the good of the whole. You simply cannot devote resources to anything but trying to out-compete your rivals and in doing so the profit for everyone tends lower and lower until you have a crisis.

I don’t believe that is accurate. Beside moons (which don’t orbit the sun), Pluto is the largest and closest dwarf planet.
