I detect some sarcasm here. But the truth is that without capitalism the entire world's population would be far worse off.
How does capitalism improve lives? This question can easily be answered by simply looking back in time. In 1820, over 90 percent of the world lived in extreme poverty. In 1990 around 30 percent of the world lived in extreme poverty. Today, less than 10 percent of the world's population lives in extreme poverty. Before the industrial revolution, the poor were lucky to find anything to eat. These individuals lacked running water, shelter, and basic sanitation. On the other hand, today the poor and rich both have access to and enjoy these basic necessities. People all across the world now have access to education, food, heating and cooling, travel, cars, vaccinations, etc. Many people bring up the income inequality argument. I believe that the true inequality is materialistic. For instance, individuals may not have access to what they believe is good food, good housing, nice cars, and cool clothes, but still have access to all of these goods even when they do not believe these goods are the nicest levels they can get. Poverty levels around the world have dropped rapidly. Thanks to improvements in healthcare and living standards brought about by capitalism, almost every country has an average life expectancy of over 70. This can be accredited to the free markets.

A third of all wealth ever created was created over these last two decades alone. Over the last 20 years, during every minute of complaining about how global capitalism has wrecked the world, over 90 people climbed out of destitution. Child mortality has fallen so dramatically that the number of annual child deaths is down by millions compared to a decade ago even as the total population has grown.
No other economic model comes close.
