Looks like the voters aren't getting anything that they want from the government in Washington.-. How come America can't fire them?

That is one of the advantages of the Parliamentary model of government: Parliament can take a vote of no confidence forcing immediate elections, or the Prime Minister can call for an early election if s/he feels it might result in a bigger majority. A third benefit is that it makes multi-party systems more valid since they frequently are needed in alliances to create the majority needed to form the executive government. Unfortunately the U.S. is stuck in a two-party gridlock and attempts to fire elected officials only result in $250 million ego trips like the recent Trumpian fiasco trying to recall the Governor of California.
