This is an opinion question, so here is what I would answer with:
The government should not place special taxes on fast food as it is how some people survive. People with low income cannot simply run to the grocery store and get everything to make a burger and fries. They must rely on large fast food chains to give them healthy, enough, food for survival.
OR...
The government should place special taxes on fast food. This would increase the prices on foods sold. This said pricing could detour the public to making healthier, cheaper food choices.
