Reality:
Jehovah's system will provide crap homes for everyone that will be what He, not they, want. The "perfect" health will not be possible. Stagnation will rule in work, since you will obey every order instead of leading yourself. No material progress will be possible, since you are stuck with old technology instead of advancing technology. And marriages will be loveless, with the husbands treating the wives as property with no individual rights (which is the surest way to get them to resent their husbands).
As for Satan's system, I would only remove the regulators that suck the life out of our economy with higher tax rates and burdens on advancing technology. For the time being, I would just let the wars run their courses and pay off the interest on the national debt. A little known fact is that more than half the money we pay in taxes is wasted on putting out needless regulations (more than wars and interest put together). With that gone, taxes will go down sharply. Technology will advance rapidly. People will get more kicks out of creating new value and marketing it than on getting high, eliminating our need to war against drugs. Crime will therefore fall (and those people that insist on committing crimes because they want to control others and ruin it for everyone would get killed as acts of legal self-defense).
Pretty soon, Satan's system will begin to look like the paradise that Jehovah only promised. And without the stagnation, excessive rules, and wife slave arrangement where the wives slaves are in submission to the husbands masters, people will have much better lives. Of course materialism will still be common, if not universal. However, it will not be a problem because people will enjoy creating this kind of value, and eventually we will have material prosperity that we can only write science fiction books about today.
And that Almighty Lowlife Scumbag Jehovah will get precisely zero credit.
