Whenever you hear about those "the world is getting better and better every day, nearly a billion people have come out of poverty in the last X years" statistics, just know, all of those people were pulled out of poverty in China, by their (kinda) socialist government.

Few people if any come out of poverty in capitalist countries and countries imperialized from the West (rather, as many people fall into poverty as get out of poverty).

Socialism is pulling people out of poverty, feeding them, housing them, give them healthcare, etc. Capitalist nations keep the global south poor in order to exploit cheap labor.

It's about trends and direction. The USSR back in it's growth days pulled 300 million people out of poverty. This is a core feature of communism, to feed, house, and heal, every single person.

Since when did India become a socialist country?

Also, there is a big difference between a socialist planet and a socialist country. China has to tightrope a planet of capitalism that would happily cut them off like it did to North Korea. They have chosen a strategy of improving its society while attracting foreign investment to keep the doors open, and it’s paying off well, as the standard of living for its people increases, and China becomes an essential part of the world economy.

They do but Socialists are working to make those inequalities smaller whereas Capitalism is working to make the inequalities bigger.
