What can a common person do to legally resist the growing despotism?
What does a common person do when what is legal is not just? Our government can make plenty legal that is not just. They can write laws to advantage employers over employees. They can write laws that advantage corporations over consumers. They can ignore and enforce laws at will. They can write laws that advantage some over others based on their station in life. Don't like it? Well if you've got six or seven figures to spend on legal fees, you can fight the legal way; in the courts.
There comes a time when the common person needs to be concerned with justice, not the law.
