I would ensure the minimum wage allowed for a family to survive on each parent only having to work ONE job, preferably only one parent would HAVE to work to get by.
Then new financial laws would be set in place, ensuring a controllable economic environment where setting up scams and border-line businesses would become extremely difficult, and also help to secure the economic future of my country.
Make the tax laws about a million times easier to understand, having only a few easy-to-use forms and formulas needed to pay the correct taxes. We would avoid a lot of the nonsense, people would understand the system and know they are not being cheated, and regulating it would also become much simpler. Would also help to reduce fraud and similar.
Have the government control the oil industry, making billions a year that can go towards improving the country and making life better for the average citizen. True, a few really rich persons wouldn't become even richer, but I couldn't care less...
And finally, attacking rival candidates during elections would become illegal. You would be allowed to present YOUR case to the people, NOT say things or fabricate things about the other candidate. Doing any direct action to hurt your rivals campaign would be treated as fraud and you would be unable to continue, and risk time in jail.
I would then adopt the Confederate flag as my new national flag, not because of any of the things the flag may or may not stand for, but because it's a really cool looking flag. I would then give it new, cool meanings.
Meatballs would be adopted as the new national dish, and genetically altered cats would be dubbed "Vampirecats" and declared the national animal.
