The US had this system, it's called Federalism.
However, Progs took over and centralized power. Now the President runs the show.
Federalism makes for a very weak country. Think how dysfunctional the congress is. Imagine trying to coordinate 50 individual State congresses. The gov't grew in power in
reaction to problems that developed. There was no hostile take over. If we went backwards we'd quickly learn why power no longer is mainly at the State level.
how so? As long as defense and interstate commerce is regulated by the feds, why do so many things need to be the same throughout the country?
Local control of things is usually better than having your life dictated by some desk-warming beancounter 1000 miles or more away.
You're letting your ideology get in the way of our history. The Articles of Confederation didn't last very long as they were too loose for the States to work together. We can't have 50 armies to defend the country. It took a strong Federal gov't to force states to return slaves and not send smoke from coal plants across state lines. The individual states were unable to put people back to work during the Great Depression so the Feds tried. Southern states wanted to keep segregation. Etc.
My history is great, how about yours?
George Washington summed up the problem with the Articles of Confederation by saying, "No money".
I have no interest in going back to the Articles of Confederation so stop suggesting I do.
The Constitution worked just fine up until the dawn of the Progressive era. It was an era where the Supreme Court had just slapped down an attempt at a federal income tax as Unconstitutional, so they just amended the Constitution to force it upon us. Then they took away the states ability to appoint a Senator to weaken state power and created their own bank with the Fed, and they were well on their way to having too much money instead of "No money".
Now the US federal government throws money at every man, woman, and child on the face of the planet through welfare, health care, international loans, etc. Now if you don't like what the US government does world wide, you may just lose your money from them. Even states are not free to do as they like least they lose their now depended upon federal funding. Now the very Republic is in jeopardy because of the outlandish debt created as a result of this crap. For you see, Progressives like President Wilson despised the US Constitution and the "weakness" you speak of, so the "fixed" it.
The Founders were wary of a strong centralized system, which is why they allowed states to rise up and challenge federal authority under the Constitution. It has never been done but if there ever was a time to do it, it is now.....or do you not like the Constitution as well?
First order of business is to limit Congressional terms. They were never meant to serve for life and have a lavish retirement and live in a bubble instead of creating a world in which they would have to live outside the bubble. There also needs to be spending restraint. Having trillion dollar deficits at a time in history where the US is not at war is unacceptable. In fact, continuing to go to war without declaring war is also not acceptable.
As President Lincoln aptly pointed out, "The provision of the Constitution giving the war making power to Congress was dictated, as I understand it, by the following reasons: kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object. This our convention understood to be the most oppressive of all kingly oppressions, and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us." Of course, the reason the US government can wage continuous war around the globe is once again directly linked to their power of the purse as they run trillion dollar deficits every year.
Obama violated the War Powers Act by not notifying Congress in a certain length of time when he went to war with Libya. His excuse was, "It's not a war".
To sum up, the problem with the Articles of Confederation was "No money", but the problem with the subversion of the Constitution by the Progressive era is, "No restraint".
