Government money is coming into the District (as well as Maryland and Virginia) whether you call it a "district" or a "state." The only thing that denying DC statehood does, is to disenfranchise the people who live here.Second, creating a state that is also the seat of the federal government with essentially unlimited funds, paid for by the rest of the nation, is incredibly unethical.
Many federal offices are located in Maryland and Virginia, and there are military bases all across the country.Third, having the population have additional representation will cause further misappropriation of funds to the capital state.
More than we already do? We don't have any. We can't even control our own city council without the dictatorship known as Congress vetoing their actions.So no thanks, DC residents don't need to have anymore representation than they already do.
