Capitalism has lead to a lot of nice things (the average person today lives better than a medieval king did) but that doesn't mean it's perfect or can't be changed. Governments ensure people can use roads for free, provide education, pay retirement pensions, and fund all kinds of other social programs. There's minimum wage, industry regulations, health and safety regulations. None of these things are really "capitalist" but they exist in capitalist societies anyways.
I think it's possible to keep modifying what capitalism is until we have a system that does work for everyone.
