And how this works is programmed into our brains.
Like I said, the people who do this are not necessarily evil (although some no doubt are), it is just that they learn early on in life that they have "it" - that sympathetic look or vibe that they give off - and that people just do things for them. They start to expect it as part of the natural course of events. And each time they get away with it, it reinforces the behavior.
But a large majority of "victims" today are not really victims at all, but just people who have been convinced they have been put upon.
While it is possible to play the victim card and posit yourself as a victim of circumstances - oppressed by unseen others, such as the big government, the tax man, Wall Street fat cats, the banks, the 1%'ers or Obama, depending on whatever political wind blows through your mind - the upshot is, it is a crappy way to go through life, and it never ends up solving any of your personal problems. In fact, it just makes them worse.
