I've been pondering on this for a while myself about what if just for the fun of it.
For sure, your first thought Bidadisndat.
Would reintroduce National Service (two years) and there would be NO exemptions. Those who did not wish to serve in the military for whatever reason would be given the option of working on projects that would benefit the nation such reafforestation, transport infrastructure, working in Nursing Homes and Hospitals, etc, etc.
Make term limits on all government. Maybe between 2 to 4 years at a time. Would not allow the scratch my back i'll scratch yours. Can't remember what that is called but yall know what I mean. Limit the amount they can make up to but not more than 100,000 a year. That way someone who really wants to work for us the people will do it not for the money but because they really want to help the people.
Implement a flat tax and end all gun control. All children must have mandatory gun classes and be taught how to garden.
Parents would have the option to home school their children if they wanted but they would still have to follow the laws that are in place now on how they pass each grade.
Next, put all farmers back to work growing food for the US only. If we have too much extra then sell it to foreign countries.
Eliminate all food additives and fillers. All cities would grow their own food so it wouldn't have to be shipped. Get rid of all imitation foods. If it can't be made by what the us can grow then it would not be allowed inside the borders.
Borders would be closed to all outsiders. For those who already in the states. Only allow those who have been here 30 years or more that have worked in the same line of work for 20 or more years to stay and make the rest go back to their own countries.
Ban all cigarettes that are made now but raise tobacco and smoke it like days of old if you just have to have it.
Get rid of credit cards, store cards, gas cards, etc. You can keep your debit card if you have a checking account but no charging of anything allowed. If you don't have the money you can trade/barter for it just like it used to be done.
Everyone would be under law to grow their own food, those who didn't have a place to grow their own food would have community gardens.
There would be no welfare period. If you are disabled there would be something you would be able to do. even if it's just for a few minutes at a time. "Other than military, see further down".
Automatic Death Penalty for murderers, rapists, child molesters, Life in prison for drug dealers unless it could be proven they murdered someone then they would get the death penalty. Make the prisoners grow their own gardens like what used to be done back when. For those who commit and are arrested for spousal and child abuse. Mandatory 5 years for first offence. 10 years added on for second offence. 3rd offence, life in prison.
For women who hurt their children, the same for child abuse but on the first offence they get sterilized.
Get rid of the hunting seasons but allow the limit on how many animals could be gotten at once and manage the herds like deer, elk, bison, etc. Basically raise them like you do cattle.
Withdraw from all wars that we are in
Give those who have served in the military free housing and medical. Those who are disabled and can't work due to getting injured in combat they get a a living wage that keeps them out of poverty.
End all aid to foreign nations.
Put limits on how much the drs can charge for health services, A limit on hospitals, emergency rooms, etc. But it be affordable to everyone.
Put a limit on how much can be charged for rent for different structures.
When it comes to alcohol and drugs, if you get 3 strikes you have to enter a rehab center immediately for a term of no less than 2 years. If you accidentally kill someone while drunk or high after you get out of rehab you automatically get the death penalty. If you still can't stay sober and you are arrested you automatically go back to rehab for life where you will be taught to make things like furniture, license plates, clothing, etc.
Like with drugs and alcohol, If you are diagnosed with a mental health problem it will be mandatory to be on medications that keep you stable. If you get 3 strikes you will have to enter a rehab center immediately for a term of no less than 2 years. If you accidentally kill someone while off your meds after you get out of rehab you will get the death penalty. If you still refuse to take your meds after getting out of rehab and are arrested you automatically go back to rehab for life where you will be taught to make things like furniture, license plates, clothing, etc.
For fun, i'd bring back all the drive ins.
For all of those who are against any of this they will be made to leave the country and will never be allowed to return.
