>Then they got rid of the super size at McDonald's.
It was a bad idea from the start because the United States as a whole is not Texas manifest. The U.S. had an obesity crisis as the fattest nation in the world (before Mexico took over), and the Morgan Spurlock documentary didn't help.
>Then they limited the size of the soda you could buy in NY.
For a time, and it was an ordinance enforced at restaurants only. You could continue to buy whatever size was available (typically 2Ls) at grocery marts and convenience stores. It was ruled unconstitutional and it is no longer enforced.
>Now they have a special tax for soda of any size in Philadelphia
Ah yes, charged at the distributor level. That means the poorest people, typically but not exclusively the people on food stamps, can continue to buy it on the taxpayer dime. A government overreach poised as a government solution for a government-caused problem: mismanagement. Cook County (Chicago) is also applying it to a broader set of products, but again, won't be taxed to food stamp holders because they pay no sales taxes on groceries.

>Mainly target the poor, this helps to keep the poor impoverished
Are you sure?
>cigarets
Pay for county-level anti-smoking cession products. The actual smoking is the main cost: the tax is extra.
>fast-food
Typically just a sales tax with an added bonus for being a restaurant, typically applied on a municipal level. Pays for sidewalks, muh roads, muh transit systems, muh municipality offices, and muh liberries. Get rid of this source of income, you have to resort to other taxes or private funding.
>alcohol
Same deal, just taxed more aggressively as alcohol is proven to be more dangerous when consumed than fast-food. Most people don't get DUIs or into fights after eating a few burgers.
