Which countries have a Parliament?

First-World countries use a parliamentary system because they are sophisticated. America uses a parliamentary system that governs its citizens through appointing Justices for the Judiciary, Executives for the Executive, and Legislatives for the Legislature. The people vote for who represents them in Parliament, so therefore, they are given representation. In 'merica, the people vote on who represents them in the national government, but what they dont know, which doesnt hurt them, is that the ultimate ruler, being the man of the executive branch, chooses who represents government for all political powers. This is how checks and balances work.

unfortunately the above answer has several inaccuracies which appear to be based upon an 'all-American' approach to answering the question _

in an increasingly globalized community where standards of living and representation are being raised significantly the term 'First-World' is actually becoming out-moded and the term 'sophisticated' has not been clearly defined either and is therefore also open to dispute _

to answer this question more accurately the first step might be to define the meaning of the term 'parliament' _ a national representative body which has supreme legislative powers within the state which it governs _

if 'parliament' is defined in this way then it immediately becomes clear that the vast majority of countries in the world have some form of parliament which governs their people through various 'parliamentary systems' of which the American parliament is an example of a republican parliamentary system
