The First Amendment (1791) to the U.S. prevents the government from creating a nationally recognized religion, as well as to prohibit to restrict individuals religious practices (which guarantees freedom of religion). It also guarantees people's freedoms concerning speech, and press and the right to assemble and to petition the government for a redress of grievances.
The capitalist economic model relies on free market conditions for the creation of wealth. The production of goods and services is based on supply and demand in the general market.
