I tend to hop between books I read, having 10 or more in progress at the same time. Therefore, when I hop back to "The Law" for my second reading, I still forget occasionally that this book was written 150 years ago. I will get it confused with books written in 2007 or 2008 (other than the slightly odd grammar), as it deals with the exact same issues which are plaguing our government today.
You will recognize very similar topics to today's government. Read about bailouts for large businesses which are in trouble, when the government should mind its own business. Read how politicians protect their power by calling people "isolationists" (though it is called "individualists" in the book) when they ask for less government interference in foreign affairs.
The thing I enjoyed the most was the crisp line which was drawn for where the government belongs. He says that people have the right to protect their liberty and property. The people also have the right to organize together as a group (IE: government) to more effectively protect their liberty and property. Therefore, "The Law" should be used only as a means to protect liberty and property. The forced liberation of any group's wealth (property) for the benefit of another group is completely against the true purpose of government/law.
