Anyhow my snippets are ngrams and fusion tables
In reverse order, fusion tables shows a link between income and smoking, really poor people don't.
Ngrams shows us what we find important, I tried music(Beatles v Elvis), Hitler, breakfast and to make it all come together tobacco .(Hitler V Breakfast here)
In a nutshell music is right at the bottom of that list, even at the very height of the pop music 60's scene, Hitler just about as important as food but despite the fact everyone is a non-smoker tobacco beats the lot!
Is this the story of the 20th century? See how eggs overtake smoking during wars, also how by the end of WWII tobacco starts a steady decline, in fact it seems to peek when the worst of the 30's depression is upon us!
Could it be that the reason the worlds economy went into free fall was the smoking habit? Could it be a combination of spending money only on the one product and its health effects snuffed out the rest of society?
This graph would seem to support another idea: that we should talk about Hitler to stimulate the economy!
I look smug as I put away my slide show , put on my coat and leave a table of the powerful reeling from this science based observation
