The Constitution is too difficult to amend, after the Bill of Rights we have amended that document 17 times, while Alabama has amended her Constitution about 800 times, so other methods have been used to keep America moving. One method is to change the laws. So each year the Supreme Court is asked to look at 8000 challenges to the Constitution and it rules on about 80 or so of the challenges. So we obey laws that might be found in error if they went before the Court. Another method is we simply change something and we accept the change and no one challenges. Another way is we see something in the Constitution that might make the change OK so again we accept the change. What would America be like if we didn't make changes, one way or another?
Alabama is a red herring! The way they have it set up everything that passes the Alabama legislature is an automatic change to their Constitution. If the legislature decides to vote on the color of fire engines and decides that yellow is is better than red then every single fire engine in Alabama must be repainted yellow in order to be in compliance with the Alabama constitution.
So no, you don't want to go there with that argument.
The SC primarily looks at cases where there are conflicting rulings in the lower courts. Their job is to decide where the line is drawn when it comes to what legislation actually means. If half the courts decide that a law allows fireworks to be sold in every state and the other half of the courts decide that the law allows states to ban the sale of fireworks in their state then the SC needs to look at the law and decide where the constitutional line is drawn. Do the people have the right to purchase fireworks nationwide or do the states have the power to regulate fireworks to the point of limiting the sales to professionals trained in the safe use of fireworks?
If a case doesn't involve that level of decision then the SC can allow the decisions of the lower courts to stand if a super majority of the court agrees. It only takes 4 justices to agree to bring a case before the court so in this instance the bar is very low for judicial review.
As far as not making changes is concerned from the original Constitution the odds are good that you would not be a happy camper. It would still be legal to own slaves in this nation and that means it would be a pariah amongst the rest of the nations of the world. Your right to privacy would not prevent the police from entering your home and ransacking it if they felt like it. They would be able to arrest you and not be required to give you Miranda rights. The list goes on and on.
