Then you have no idea what the governments role should be. It's role is not to regulate industry but to create an enviroment where industry can flourish and to insure the nations security.
If you don't like the steak sandwich you ordered then you have the freedom to choose another sandwich shop.
A wise and frugal government, which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned. This is the sum of good government, and this is necessary to close the circle of our felicity. Thomas Jefferson, First Inaugural Address.
I know this is probably and exercise in futility..but what the heck:
Preamble Note
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
Section 8 - Powers of Congress
The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;
To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;
So let me break it down for you..
Insuring the sandwich shop sells safe food:
-Promotes the general welfare by insuring that the food is safe to eat.
-Promotes commerce because customers will return to the shop..to buy from them again, and not to lynch to shop owner.
-And both are well within the powers of congress.
James Madison stated that the “general welfare” clause was not intended to give Congress an open hand “to exercise every power which may be alleged to be necessary for the common defense or general welfare.” If by the “general welfare,” the Founding Fathers had meant any and all social, economic, or educational programs Congress wanted to create, there would have been no reason to list specific powers of Congress such as establishing courts and maintaining the armed forces. Those powers would simply have been included in one all-encompassing phrase, to “promote the general welfare.”
general welfare
“If Congress can do whatever in their discretion can be done by money, and its (sic) will promote the General Welfare, the Government is no longer a limited one, possessing enumerated powers, but an indefinite one, subject to particular exceptions." James Madison, Letter to Edmund Pendleton, January 21, 1792
"Congress has not unlimited powers to provide for the general welfare, but only those specifically enumerated." - Thomas Jefferson
"With respect to the words general welfare, I have always regarded them as qualified by the detail of powers connected with them. To take them in a literal and unlimited sense would be a metamorphosis of the Constitution into a character which there is a host of proofs was not contemplated by its creators." James Madison, Letter to James Robertson, April 20, 1831
