Do you think the fall of the Soviet Union was a good thing for the world as a whole?

Al Gore in a recent Op-Ed in the New York Times stated:
“The decisive victory of democratic capitalism over communism in the 1990s led to a period of philosophical dominance for market economics worldwide and the illusion of a unipolar world. It also led, in the United States, to a hubristic “bubble” of market fundamentalism that encouraged opponents of regulatory constraints to mount an aggressive effort to shift the internal boundary between the democracy sphere and the market sphere. Over time, markets would most efficiently solve most problems, they argued.”
He goes on to point out this caused the possibility of legislation on climate change to seem like restraints on the market, so no action was taken.

What are other ways in which the fall of the Soviet Union may have been a bad thing for the world? Do you think it’s important for the health of the world for there to be multiple superpowers keeping each other in check?
