I agree with most of what you said except a few points.
1. I'm not sure we actually have to force people to work longer only because we liver longer. Due to technological advancements more and more jobs will be done automatically. Ofc this creates a lot of new jobs in other sections such as computer engineering. But ye, it takes 1 man to program a robot that will do the work of 10 other men basically so the amount of jobs will drop rapidly. I got no indepth knowledge on this though so i can't be sure, correct me if i'm wrong.
2. While i believe free immigration have many positive effects, i'm still a racist and i don't believe in a multiethnical society. It could work with whites and mongoloids (chinese, japanese, koreans, etc) i guess but i just still don't see it being worth it. Trying to integrate arabs and blacks with white people has proven to be impossible over and over. After 300 years it still don't work out well in USA and the integration in Europe is currently a DISASTER. We see immigrants being extremely overrepresented in criminality and uneployment statistics while the segregation is huge, i don't think anyone denies this irrelevant of political colour. I believe this is partially because different ethnical groups simply can't live next to each other, in history it always ended up with one group taking over more or less. We see white flights from immigrant suburbs for example.It's also partially because arabs and especially blacks ain't suitable in a white society, we are just too different. Free immigration between white countries is ofc okay and should not only be accepted but also encouraged.
I only talk about arabs or africans as a collective and not as individuals. I know that a lot of people from these groups do just fine in our countries but if you look at them as groups, it's a total disaster. And that's what you have to do, you can't look at people as individuals when you are talking immigration, it's just too big scales. Also since i believe it's genetical, you can't just keep the "good" immigrants because their genes is the problem, not them as individuals. They will still spread their race which will have a negative impact on our countries in the long run.
Unlike most racists i'm not against a globalized world though. I believe it's a natural effect of technological advancements and brings nothing but good. A country can still be a big part of the globalized economy without resorting from being ethnical homogene. Japan is in my opinion a perfect example of how a country should work.
Before you start opposing me i recommend you to listen at this man
http://en.wikipedia.org/wiki/William_Luther_Pierce . He sums up what i think much better than how i explain it here.
Edit: Also some other points i like to add on:
*Stop internet-censuring laws such as SOPA and ACTA, they bring nothing good whatsoever while they have a HUGE negative impact on free speech and democracy.
*Legalize weed
