(D) higher taxes on the rich
The taxation of rich people's fortunes is an important topic for the economy because it involves taxation, one of the main means of collecting the state. Whether or not to tax large fortunes is a delicate matter and involves distinct interest groups.
Those who advocate taxation argue that the government will have more money to invest in public and social policies, which represents a transfer of income from the richest to the entire society. Those who are against, argue that this measure will make companies invest less in the economy, which will decrease jobs and GDP.
Therefore, this is an extremely relevant debate that involves large economic impacts.
