Prior to the printing press, there were only 30,000 copies of books in Europe and 75% of them were in Latin. The printing press made it possible to print more books in multiple languages which helped increase literacy and education throughout Europe because books were more accessible. The New Testament was also translated into German by Martin Luther. However, the Church did not like the printing press because it made it impossible for them to censor books. This means that authors were able to spread new ideas about science and religion which the Church did not agree with. While the spread of new ideas helped revolutionize society during the Renaissance, it created a lot of controversy with the Church.
The true vision of Karl Marx about communism is something that objectively would never work in practice. The problem is that the human nature and the Marx's vision of communism are not going very well together. According to Marx, all people should be in the same hierarchical level, thus horizontal hierarchy. Everyone should be paid equally, no matter the type of job, and everyone should get the same services. There's no private ownership and the economy is totally controlled by the government in a manner to be self-sustaining. Big problem in these things is that the humans stride toward progress and success, so by putting everyone in the same basket the creative minds and the successful people are destroyed, while the lazy ones, and the ones that do not have great potential get the benefits without deserving them. The economy can simply not function in a manner to be self-sustaining, and it will always be on the verge of collapse, and there will always be huge problems with lack of food and products.
