I use to be pretty libertarian in my views on sugary drink and fast food taxes ... but at this point, its a major blight on society and people truly can't help themselves. My spouse works in healthcare and often is involved in caring for diabetes patients - they literally pick soda and sweets over limbs. They'd rather consume mountain dew and ice cream vs keeping their arms and legs. Even when doctors prevent food/drink orders with sugary crap, their friends/family bring in more garbage. The number of obese people walking around and density of fast food places in urban areas is utterly disgusting. Explore around google maps in big urban areas, or even small ones - you can easily find 20-30 fast food places in towns of less than 30k people. Easy property tax revenue I guess?
