The following ideas are not original with me, although I have expressed similar ideas in the philosophy section of my website,

If you view these ideas as self-evident then you are a realist. If you wish to have the governments force working people to support people who can work, but choose not to work, then consider yourself as live bait for the next big fish that decides their government program should extract its pound of flesh from you.
