Laissez Faire capitalism
I support limited government, not Laissez Faire capitalism. Government needs to be there to regulate business, to take care of disabled people, and also should provide a security net, because everyone can be unlucky. However, often the government does way more than it is supposed to do. For instance, why should the government regulate the amount of hours I want to work. Most countries in Europe does, and it's not 65 hours, but 35-40 hours.
End drug prohibition
Never, it would make it possible to sell hard core drugs over the counter. Some kids may end up buying this stuff and ruin their lives. People don't need drugs anyway.
Avoid interventionism in foreign policy
Should be an ideal, but not always possible.
End foreign aid
No, but the nature of foreign aid should stop. Government should try to open up for free trade and should help countries develop. A lot of foreign aid only helps a country for some few years and doesn't have an plan for how the country is supposed to support itself.
End gun bans
No, cause then it would be legal to have mentally unstable people walk around with a AK-47, loaded.
Deregulate healthcare
I think he is talking about completly deregulating health care. I actually support the public option, because I'm uncertain if private health care actually works. However, we have experience from many other countries that public health care with a private option works ok. Reality is, health insurance in the US costs the same for the public, but way more for the private person. Also, not everyone is covered.
Better to deregulate other places. For instance US should open for more charter schools and allow more competition between schools. In many ways the american school system is quite left-wing.
Semi-amnesty for illegal aliens(work for amnesty)
Never, it will only make more people cross the border. I think it should be easier to come the legal way, and illigal alians should have a harder time. For instance illigal alians should be kicked out when they get health care.
End welfare
No, government must be there for people who can't take care of themselves.
Allow opting out of Social Security
You mean by not having to pay for social securty, but you also won't be provided any services. No, because government works because everyone that can contribute, contributes. Hence, everyone should pay. However, I see something good about it. It will then be restricted to the people who are sick, or else people won't pay. In many countries, perfectly healthy adults are living off other peoples tax money.
