I just read the world has a surplus of sugar

Question

1: Is the domestic price of sugar equal to the world price of sugar

2: Does the USA allocate quotas for imported sugar

3: Does the USA protect domestic price of domestic produced sugar, by limiting imports of sugar

4: Does the USA farm bill vastly enrich a small number of families that control the majority of cane sugar production in Florida

I have visited the sugar cane fields and processing plants in Florida, but nobody could explain the pricing mechanism

Did I ask the correct questions??
