Why do all states not have bicameral legislature?

[I]n the state context, I think there's a relatively easy way to do this—have fewer legislators! At the national level, we have a bicameral legislature because of the overall workings of the federal system. But the non-Nebraska states have bicameral legislatures for no real reason. If you simply eliminated the lower houses, you'd end up with substantially fewer state legislators. Then you could pay them more and offer them more staff. It'd also be easier for citizens to keep track of who their elected officials actually are (can you name who represents you in your state legislature?) and make the electoral competition for the seats more fearsome.

Open question: why do states have two chambers? (Seriously).

The U.S. Senate is the product of a compromise between the states. Why do states need to emulate that model? Going back even futher, do we want to follow the lead of a parliamentary system where 1/2 of the leadership was traditionally filled because of birthright? I'm a big fan of the U.S. Senate. I just don't get why there needs to be a New York Senate.
