The profit motive is an exceptionally inefficient motivator for creating quality goods and services, while producing based on needs often results in more risks being taken and a higher quality end result, as the goal is to fulfill the need and not to take a profit. It's easy to see the failures of Windows over time vs Linux when it comes to being a quality OS, but this extends to Socialist economies like the PRC, which despite being a developing country has developed far better and more extensive infrastructure than the US, such as a robust High Speed Rail network. Even Cuba, with all of the sanctions and embargoes, has one of the best healthcare systems in the world. When compared with economic peers, it isn't even close.

What Capitalism brings is massive disparity, centralization of Capital, a fusing of bank and industrial Capital, dominance of financial Capital, Imperialism, de-industrialization, stagnation, and then crisis. Socialism is that next step beyond Capitalism where Humanity directs production according to a common and deliberate plan, rather than submitting to the chaos of the market and the plunder it requires to be satiated.
