How would life in the US be different without the preamble to the constitution?

Before this question is answered, let's show everyone what the preamble to The United States Constitution says.

"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

So, what does this do for The United States? Well, in all honesty, nothing. This is simply an introduction to the constitution and states the intention of the documentation and does not grant anyone any power. However, it can be interpreted in such a way that could help an argument in a legal dispute.
