Can the Federal Government Do Whatever They Want?

The Federal government is limited by the constitution and the laws of congress.

Nope.

The Constitution of the United States spells out what powers and authority the federal government has. It is what is known be legal experts as a GRANTING document, in that it is assumed that the federal government does not have the authority to do something unless it is specifically provided for in the Constitution and the US legal codes and statutes that are derived from it.

Conversely, state constitutions are LIMITING documents, as it is assumed that a state does have the authority to do something unless it is specifically provisioned against in the state constitution, and the state legal codes and statutes.

Finally, you should not confuse socialism with totalitarianism. Socialism is a type of economic system, and does not necessarily require a totalitarian government to operate. There are plenty of socialist democracies in Europe. Likewise, a capitalist country is not necessarily a free and democratic nation by virtue of it's capitalist economics. Countries like South Vietnam, South Korea (until about the 80s), Iraq, Haiti, and a plethora of Latin American and African nations all operated with capitalist economics, but were politically totalitarian dictatorships.

If the federal government is operating under its enumerated powers which includes immigration and for Congress, providing for the general welfare of the population, guess what? It's not only constitutional, it's the way the founders wanted it.

Yeah, you see theres all these good things we want to do, things that need to be done; but we can't because 240 years ago people who lived in a different world set the rules. It's not for us to think for ourselves, our duty is to follow what they said without question, without regard to anything.

See what they wrote was written for a different world, a world that no longer exists. Their system has lead to wars, constant bickering, fighting, confusing, expensive litigation, we're constantly taking today's issues and looking back to see what they would have thought about it 240 years ago; constantly fighting about states rights vs federal powers.

Why cant government work together, why do they have to be constantly fighting because 240 years ago people thought the only way to have freedom was to have almost no government, to have it be ineffective and weak, and then to set the system against itself with constantly battling forces.

They already do at least they try too. They form many bureaucracies that just pass regulations and "rules" and ban things with out any consideration of the law. They also appoint the people who lead them and the public has almost NO say in what they do.

they are already doing this...its called Socialism
