One form of economic pressure would be each person's civil disobedience and recognition of their rights. In the history of the world, it's these small incremental changes, and abolition of rights, that lead to complete and total change for the worse. Nazi Germany didn't happen over night.
My question is this:
Where do you draw the line?
When they make you strip completely naked in a private room and it takes 4 hours to get everyone through security?
When you are not allowed to carry ANY items on?
The full body radiation scanners does a little radiation but radiation damage to the DNA is cumulative.
If more and more people refused, this would be pressure for change.
