Answer:
The Industrial revolution is what many consider to be what began the modern era of most European societies, but few people agree on an exact date when that revolution became manifest. Some connect that loosely with the revolutionary scientific discovery of Antoine Lavoisier in France, which proved, among other things, that alchemy was an impossibility. Others point to events around the American revolution, or the "Glorious Revolution" in England.
Still other opinions say that we only became truly modern with the advent of the atomic age or even the space age in the 1950s and '60s. In artistic terms, the end of World War 1 is used in western art and music as the general point after which artists are referred to as modern. In religious terms, however, opinions for the most part go much further than that. Modern Rabbinic Judaism, for example, usually refers to the development of the religion since the compilation of the Talmud, around the 6th Century CE.
In paleontological terms, "modern" could refer to the period of recorded history (up to about five or six thousand years ago), or up to the earliest specimen of Homo sapiens being found in Africa and the Fertile Crescent (up to 100,000 years agoor more).

The Soviets were proclaiming themselves as communist, though the reality was not as the communism truly says a state should be run. If the Soviets practiced the textbook communism, then everyone in the society would have been equal. Everyone was going to earn the same amount of money and get the same things necessary for life without any problem. The economy would have been self-sustaining and that was going to be supported by excellent planning. There were not going to be social classes, but everyone would have been in the same class. The Soviets did pretty much everything wrong with those ideas, and in all fairness the human nature just doesn't allow for something like that to exist.
Mikhail Gorbachev was hated by the hardline communist. The main reason for that was that he was trying to make the country slightly more liberal, more open to the world and to modernization. That was seen as treason of the communist ideology by the hardline communist so they were against all of that.
