Seriously, I really would like to know what you think and I promise to think carefully about what you say.
First, I think there are other plausible and immediate options. Having read the Green Party's platform, this call for environmental-based communitarianism...it is viable. A more Nordic model could easily be adopted (though it isn't El Dorado). There are other ways if Jeremy's models seem not to fit the bill.
Two, I think what we need in Britain is a thorough and heartfelt examination of what we want to be. We need first-and-foremost to bury the Empire. It wasn't that good, and it is gone. It is what it is. This doesn't mean we are of less value.
I firmly believe that Great Britain's chief strength is in science, and always has been. I usually launch a long laundry list of British (and immigrant) led scientific discoveries, but it can get tedious. It is not in real estate or football. I think with technology and rationality Britain can absolutely be any thing it wants to be (not an Empire, however).
I think as individuals, and I think this is of utmost, vital importance, we must each look closely at ourselves and ask "what makes me content/happy?" The answers will vary greatly, but I think there will be common themes:
We want to be safe, and for our families to be safe. We require a certain amount of food and clean water. We require, at our latitude, clothing and housing to keep us warm and dry. Our species seems to function better given a certain mental stimulation, be it from study, work or socialising with others. Our society functions better when we receive care when we are sick or old or disabled. These things make us feel secure and safe, vital for contentment/happiness. Loving another person and having them love you.
There are other things. Transport, consumer protection. Heck sewage and rubbish removal, not glamorous it's true. There may be comfort in material items, a warm cup of tea, a song. A holiday. There is nothing wrong with that, we are human.
These things make me happy. But how can I fully be content if I know that these basics are not available to others? I would, in fact, enjoy them much more, and be more content, if I knew everyone had these things.
And crucially if I expand my wants, my requirements for happiness, too far away from these things, what does that say about me? Could I be perfectly content with three houses knowing that there were some without a room?
I am not sure that we are viewing things the right way around at all. Why not turn it all over and make as our goal that every person has these basic requirements for happiness and contentedness? I think we can do it.
And I think once this is done, everything else will be a marvellous and wonderful treat. Everything added on top of that could be enjoyed fully, with the knowledge that no one is doing without those basics requirements.
