Why is the house of commons more important than the house of lords?

the house of lords is where all the politicians meet, the house of commons is where ordinary people debate. No, the above is not strictly true: I refer to the bi cameral Parliament of the UK. The Commons is the principal House, and is where the government sits, made up of the elected representative MPs. The House of Lords is the upper chamber and has a role of overseeing the work of the Commons, it was originally made up of heriditary peers, but now is largely made up of Life peers & the Clergy. It is unelected.
