Answer:
An idea that would most likely be held by a member of the Democratic Party would be that the government should help make the economic system more fair.
Explanation:
In the 21st century, the dominant ideology within the Democratic Party is modern liberalism, progressive liberalism with support for a welfare state and a mixed economy.
Democratic voters defend the supervision of the economy by the government, so that it can remedy the mistakes caused by the market and thus avoid any kind of damage that can be caused to society. For this, the government must collect more taxes, which is seen as something logical and positive by Democratic voters. It is, in short, a much more progressive political platform than that of the Republican Party.
In turn, this political group prefers that the United States maintain non-interventionist international policies, but rather collaborative relations with different international organizations in political matters.
