The fact that interest groups favor the wealthy and well educated can be understood as a reflection of what eternal dilemma in american politics? liberty is often inconsistent with equality. democracy has not been in reducing the number of factions. there are no efficient means of organizing the working class in the united states. organized associations and groups inhibit freedom. it is difficult to have majority rule and also protect minority rights.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
