Answer:
Manifest Destiny was the idea that Americans, that is to say, the United States, had the right to expand to the West, and reach the Pacific Ocean: occupy the lands in between, and spread American values.
It also applies to other parts of the world in a more indirect way, especially Latin America.
The settlement of the West was aided both by economic necessity, because many migrants were arriving in the United States seeking for cheap land, and also by ideology, and the ideology was precisely that of Manifest Destiny.
The federal government supported the interests of big businesses over the interests of labor unions.
Unions became popular during the Gilded Age in the US during an industrial boom. The government supported the owners of business during this period and practiced free market capitalism.
During the Gilded Age, the government took a policy of free-market or laissez-faire capitalism. This means the government did not interfere or create regulation of the economic system. They tended to support the practices of corporations because they were wealthy and had power. Unions demanded higher wages, government regulation, and better working conditions. All of these demands went against the thinking of the time and would have cost the government money and the favor of the powerful in the country.
I believe it's camelot. Sorry if I'm wrong.
