Capitalism or Communism?

Winston Churchill once said "The vice of capitalism is that it stands for  unequal sharing of blessings; whereas the virtue of socialism is that it stands for the equal sharing of misery."   Socialism being a politer word for communism.  Why is this? 
    Communism was invented to "level the playing field" by taking everything and dividing it equally and sharing it equally among all the people.  The biggest down side of  Communism, why even the Russians gave it up in 1989, is it gives no incentive to anyone to work hard.  Why work hard when you get paid the same for slacking off?  Other downsides come when ordinary fallible people take up the divide and share business.  Being fallible, these people skim plenty off the top for themselves before  doing any sharing.  Since nobody works very hard, there isn't much to share in the first place. 
  Under capitalism, people are allowed to own stuff (land, houses, factories, everything) and to keep the proceeds.  By hard work, or genius, it is possible to become wealthy, powerful, and important.  This motivates a lot of people to work really hard, take risks, invent stuff.  The overall result is a never ending fountain of material wealth, food and drink, clothing, shelter, toys for children and grownups, all at decent prices, and vast quantities.  Aided by capitalism's law of supply and demand which efficiently matches production with demand.  The entrepreneurs who create all this goodness get to keep a goodly share of it, but there is enough that everybody gets some.  Compare the standard of living for ordinary people in communist places like Cuba, Venezuela, Russia, with the standard of living in the United States.  This is why the United States has an illegal alien problem whereas the Communist countries have long lists of people wanting to leave, and not permitted to.
    This is what the Cold War was about, the Russians wanted to convert the entire world to Communism and we wanted to keep the entire world capitalist.  We won, and the wonder of our victory is that we managed it without touching off the Last War with the Soviets.
