Innovation is also becoming a meaningless word to defend the system, the innovations have their foundations fostered with public money, through funding of scientific research which is then later captured by the industries to develop products. The innovation is productionalising another innovation, the foundation is built mostly on public funding. Very few companies actually do ground-breaking research that innovates, they're pretty risk-averse in this sense, the productionalisation of those discoveries has its own value, not questionign that, but it only gets traction afterwards when the brunt of the work of discovery was done.
Efficiency of markets is a hypothesis of financial economics with much better written criticism than I can write here, Warren Buffet doesn't believe in it, for example. It's not a given whatsoever, nor proven empirically.
