You may believe each person should have equal access to resources and receive equal pay. You may be one of those that takes it to the level where the concept of "Pay" should not even exist. You may not be. You may believe that someone else getting more is them hoarding resources or wealth. You may not believe in the concept of private property, and in fact if you are truly a fan of communism you should believe that.

However.

If the revolution happens I assume that means you are volunteering to be...

The hazmat cleanup person.
The crab ship operators (one of the most dangerous jobs out there)
The fire jumpers.
The garbage man.
The sewage treatment operator.
The street sweeper.
EDIT: The nightman (with the return of being able to legally defecate on the streets in many liberal cities we need to resurrect the old night man/soil man job of the person who goes around each night cleaning up the human feces)

Remember in communism there should be equal access, and no special rewards.

I doubt in the communist land you'll find many people that desire to take on the unpleasant and perhaps looked down upon jobs.

So who will do them?

Will you have to force people?

What incentive that goes along with their human nature and even biological imperative would convince enough people to voluntarily do these tasks?

Will they do it simply due to pride in communism? Kind of like pride in nationalism, or imperialism?

This is a simple question I'd think anyone considering communism (and even socialism) would consider.

Yet I note there generally is not a lot of long term thinking done by people that push for such ideologies. It seems more based upon short term gratification, or idealized imaginary views of the world in their minds that leave out so many things in human nature, ignoring the dangers, and the unpleasantries. They also ignore the fact that it is likely the only way many of these things can be accomplished is via force. So who get's to decide who is forced? If they get to decide then is the environment truly equal or are there some with more power who get to dictate how others must behave? If there are not those that decide then how do these necessary but dangerous or unpleasant tasks get done? How do you insure you have enough people to do these tasks?

This is easy to solve when we are not talking communism. We simply pay them more, or the rewards of their product (such as crabbing) are so valuable that the danger they put themselves in when weighed against the potential benefit is deemed as WORTH IT to them. No one has to force them to do it.

Yet how would you do that in communism?

Trickle down... why work hard? Again pride? What incentive is there? If I can receive what I need without doing anything special then why would I choose to do anything special? Sure there would still be some people that would choose to. Yet let's be real. They would be very few and far between.

Mostly the answer is force. Also known as involuntary. Also potentially known as slavery.
