Socialism was literally created within the failures of capitalism after the French revolution and then all over the world. It is a workers movement. Capitalism is an extension of feudalism. We literally still use the term landlords. Workers get the majority of the value of their labor stolen from them and extracted into the pockets of people who do not work for a living. Even Adam Smith had complaints about capitalism and he would be horrified to see what the inevitable result of it is: Plutocracy
Society is falling apart because the environment is being completely destroyed and the majority of the humans are living in squalor in order to keep profits high. Latin American countries Have been repeatedly destroyed by capitalism exploiting the poor to extract resources and the value of the labor they provide.
The philosophical theory behind Capitalism is gatekeeping concentrations of wealth and growing them further. It facilitates and encourages concentration of wealth and therefore power.
Socialism is literally putting the means of production into the hands of the people who actually produce and not those who have their name attached to a bunch of pieces of property and bank accounts.
