The financial hurdles do exist - but it is mostly the political lobbying that prevents a real attack on obesity in the US. Sugar is big business and, by extension, obesity greases a lot of people's palms.

The US could take a serious look at addressing massive over consumption - but the last serious take on that was the sugary drink ban in NYC and that turned into a "you'll pry my big gulp from my cold dead hands" affair pretty quickly. The US is in too deep celebrating the exploitation of the health of their populace to turn things around - but other countries might have a chance.
