If you're wondering why there's been so little innovation related to the ideas of Marx and Engels, it's probably because most people decided those ideas weren't useful. Over the past century, a lot of people tried to implement the ideas of Marx and Engels. People tried different versions of communism in different cultures, different geographical regions, and different levels of technological development. On two occasions, people even split a country in half and ran one side communist and the other side capitalist. In every case, the citizens of the communist regimes ended up worse-off. If we've learned anything from these experiments, it's that Marx's ideas reliably create failed states. There are probably better systems than what we have today, but they're not close relatives to communism. Fortunately, many far leftists have understood this and gone searching for other ways to improve the lives of the poorest. For example, basic income seems to be growing in popularity.
