Wait, "Utopianist Technocratic Party", wasn't that the robot guy who sat at that table in Star Wars episode two? He was all like "you have our support beep beep."
For the record I should note that I am no longer in the UTP, I have formed the Forward Party late last year. Both are technocratic parties, the first was for international technocracy, the second national technocracy. This means we work on advancing our own culture (eliminating our own faults and replacing them with technocratic ideas one by one) instead of trying to fight every bit of "cultural corruption" or "cultural manipulation" head on. It is hard enough to advance one's own culture to technocratic standards, but we were trying to find ways to progress even lesser developed cultures with ourselves as one common people.
what is the differnce between a selfish interest and a non-selfish interest? What is "the good of society" and who get's to decide?
It's all about motivation, socialization, quality and practicality and the limitation of wealth per individual. Wealth is essentially power, it is funny to me to see some of you folks so against autocratic systems (not saying i'm for an autocratic system at all), yet you wish to impose no limit on wealth which ultimately achieves a similar power.
What constitutes harmful?
That which is harmful is unhealthy, that which is helpful is healthy... physically and mentally. Science has told us these truths.
What constitutes corruption of great things in life? Who get's to decide what great things in life are? Who get's to decide what something's 'true meaning' is? More importantly, why can't I decide what is and is not great on my own?
We are getting very general here, but the above stands. Aside from these unhealthy activities that are deemed unhealthy by science you still pick your own interests. Once psychological control is eliminated you will then have more options in interests and resources to feed your interests. You will actually be a man with more freedom.
Do you think it neccisary to kill me to stop me from smoking?
This is absurd. Plenty of plans by the government can get people to stop smoking in a healthy way. This is far down the road but I can give you a general overview of the plans.
*It is important to note that this is far down the road after much healthy as opposed to manipulative socialization has been implaced. So it is useless to jump immidiately at this and say people will never accept this because they would be in a different mindset, especially after they recieve good social benefits. I will list different alternatives starting with the most extreme (my favourite of course /

\ ).
Option A (Forward Party's technocracy)
I. Announce the plan of the end of smoking to the public.
II. Make the citizens aware of their last year (or two) of smoking. The government would provide free cigarrettes. The first month, lets use January, they would receive many packs, and each month it would descend until december where people would receive their last pack. You could even have a grace period of allowing one more pack for the next three months or whatever.... the experts would have to work out the details on what would be the safest and easiest. Even if people took cigarrettes that didn't smoke to make some extra money, it would still be a means to an end. Of course, in an honest society this wouldn't be much of a problem, in our current society however, I still think it would be worth the cost.
Option B (intermediate compromise)
Disallow the manufacturing of cigarrettes, but allow individual citizens to make them without machinery. This will dramatically reduce socialization's affect on promoting smoking.
Option C (practical capitalism (or technocratic capitalism))
*Allow extra free social or economic benefits for those who don't smoke.
*Put extreme taxes on the tobacco companies and use that money for health education.
*Outlaw all ads by these companies.
