What are two examples of how good surplus changed life for villagers

One example how good surplus changed life for villagers is that it allowed them to use the surplus to trade other villages for goods that they otherwise would not have access to. Another example is that as a result of the surplus, the villagers no longer had to spend as much time creating those resources, so they could focus their time on innovating or learning skilled labor such as carpentry, blacksmithing, etc.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
