Final answer:
Karl Marx believed that class conflict was inevitable due to the struggle between classes being the root of all historical conflicts. He predicted that society would eventually replace current economic systems with socialism.
Step-by-step explanation:
Karl Marx believed that class conflict was inevitable because he saw a historical pattern in which revolutionaries toppled elite power structures, leading to a more egalitarian society. In this pattern of change through conflict, wealth and authority eventually became more evenly dispersed among the population. Marx argued that the struggle between classes was the root of all historical conflicts and predicted that society would eventually replace current economic systems with socialism, where the public owns the means of production.
