Of course it's just a process. Capitalism is a process which centralizes surplus and power, i.e., increases inequality, and communism is a process which decentralizes surplus and power, i.e. decreases inequality. Calling communism unrealistic and disastrous is again just being diminutive.
Communists want for people who do productive work to have an equal say in how work is done and what happens to the product. Not complicated, not unrealistic, and certainly not an inevitable disaster.
In empirical terms, there's a lot more evidence for the disaster-causing tendency of capitalism than communism. At the very worst, the end result of communism is empirically unknown, since, to date, communism has not been allowed to flourish on a noteworthy scale.
