I don't like having a lower and upper house. I say we have 10 regions, house representatives allotted by population, 20 House Representatives, and 10 Senators. The House and the Senate are equal and function in the same style as the US.
You realise that this is a bicameral model that you're advocating - quite literally, a "two house" system? The House of Representatives is a Lower House and the Senate is an Upper House.
Correct me if I am mistaken. I thought a Lower House denoted that the house is lower in stature or rank then the upper house. If that isn't true, then I take back my statements and pose another question:
Why is it called a lower house if it is equal with the the Upper House?
As MaxQue said, it's historic - in Britain it's the House of Commons and the House of Lords and stems from these back in the previous centuries. The Commons being elected by the people - literally the "Commoners" and the House of Lords comprising of people of a particular "Upper" status in society. At least, I'm pretty sure that's how the terms "upper" and "lower" came about.
