It sounds like the plan is for this ship to be the first of several, so the question is how much of that $20 billion investment is for upfront costs (design, shipyard upgrades, construction equipment) that will not be duplicated in subsequent ships. As it is, the first ship looks to probably at least break even or even make a decent profit (provided it works as expected) with bigger profits hopefully to follow. I am sure these numbers have been gone over very carefully. You don't make an investment this large on a whim.

The experiment is still going on in North Korea and Cuba. I think what we saw in the Soviet Union is actually the middle road. North Korea shows us what can happen in the worst case scenario, which Cuba shows us the best scenario... which is still not great.

Look at manufacturing and worker coops. Some succeed, some fail.

Yes. Because they are voluntary. When the government forces communism on you, it is not.

He consider our society do not respect Islam, so violence is a normal outcome

Respect is earned.
