1) Every native-born couple should be required to have 3 children. No exceptions. Kid is going to be born with his lungs next to his eyes? Still has to be born.

2) Brings me to point 2: outlaw abortion.

3) Public ownership of natural resources (Norway is an excellent example).

4) Instill national pride from cradle to grave. Encourage people to attend military parades and to sing patriotic songs at sporting events. Patriotic songs should also be played on the radio and on television. Penalize those who refuse to take part.

5) Utmost respect for the flag.

6) Cut immigration down to 0.

7) Outlaw deviant ways of dressing and speaking (no emos, pls).

8) Penalize those who choose to go unmarried.

9) Discourage the consumption of meat and lard.

10) No unkempt streets or houses.

11) Every household should have at least one well-behaved dog. This dog should be walked for 1 km at least four times a week.

12) Encourage domestic travel in order to build a sense of national unity.

13) Large, imposing statues and pieces of art should dominate city squares.

14) Discourage the use of spices in food (spices is linked to deviant behavior).

15) Encourage extended families to keep in touch and care for each other.

16) People should be encouraged to exercise at least four times a week.

I've thought about these for a while now. I think that instituting even half of these would solve over half of society's ills.

EDIT: Just saw that OP only wanted one opinion. In that case, number 11 is the most important.
