Answer:
The most likely problem to arise due to a shift from socialism to capitalism is unequal distribution of wealth.
Step-by-step explanation:
In a socialist system the businesses and properties are owned by the government. The government ensures equal distribution of income and wealth in the society.
However, in a capitalist system the business and properties are owned by private individuals. People earn income on the basis of their contributions. The government does not interfere in the economy, it's the market forces control the economy.
In a socialist system income redistribution takes place from rich to poor. Such things do not happen in capitalism. So people are mostly to face the problem of unequal distribution of wealth through this shift.
