What do you think will happen if-

[New_Conservative]

Marijuana was legalized nationally? Would there be any big changes in the economy/national debate/ what people complain about (stuff like too many people in prison, crime rate etc)?
-would it actually change American society/culture in any way (like the New Deal, the car, sliced bread, a war with a draft or Rock 'n Roll)?

If Marijuana was legalized, I don't think much will change. Tobacco use will go down, and our prison systems will be less congested with people that don't belong there. I don't expect much of an economic boon from it, like a lot of people. Pot use would go up, of course, but I don't see a big cultural impact of its legalization, considering how widespread use of it already is.

Abortion was made generally illegal in most/all circumstances I most/all states?
I'm pro-life, but not in favor of a federal law banning all abortions. I think it would be a public health disaster for women. Going back to the days of women having to go in back alleys for abortions would not be good.

Social security was privatized?
[b[A more efficient system is created for those wishing to invest in their retirement. A shot to the arm added in the economy due to the amount of money being invested into the financial system.  [/b]

Cap and Trade was implemented as compared with Obama's policy or with doing nothing?

Adamaged economy.

The "flat tax" or Reagan's 1987 tax code was implemented?

People's rights are improved, more efficient tax systemp
