What are the most critical problems of capitalism?
Capitalism has been criticized for establishing power in the hands of a minority capitalist class that exists through the exploitation of a working class majority; for prioritizing profit over social good, natural resources and the environment; and for being an engine of inequality and economic instabilities.
What are the most critical problems of communism?
Communism, as a political and economic ideology, has faced several critical problems throughout its history, including:

1. Inefficiency in the allocation of resources: The lack of a market-based pricing system often leads to inefficient allocation of resources and a lack of incentives for hard work and innovation.

2. Lack of individual freedom and initiative: The emphasis on collective ownership and control of the means of production can limit individual freedom and creativity.

3. Poor economic performance: Many Communist countries have experienced sluggish economic growth and widespread poverty. This is partly due to the lack of incentives for hard work, innovation, and entrepreneurship.

4. Corruption and lack of accountability: The absence of a free market and competition can lead to a lack of accountability, which can contribute to corruption and the abuse of power.

5. Repression of dissent: Communist governments have been known to suppress dissent and opposition, using force and intimidation to maintain control.

6. Inequity and unequal distribution of wealth: Despite the goal of creating a classless society, many Communist countries have faced significant income inequality and unequal distribution of wealth.
