If you want to say that all lawyers are evil, without any evidence, at least have the conviction to say that.
If you want to imply that some undefined minority, or possible majority, of lawyers may, or may not, potentially be paid arsonists, but might also not be arsonists, paid or otherwise, then... I dunno, maybe say something worthwhile instead.
One shouldn't draw the conclusion that lawyers are evil. Instead, it's a generalized principle: humans find ways to rationalize their participation in any system which awards them wealth and status, whether it's a little or a lot. Some patent attorneys know that patents are bullshit and profit from them anyway (whether on behalf of the trolls or the little guy), many internalize the belief that they are defending genuinely deserved intellectual property rights. There is a tendency for people to look at whether a system does well by themselves and their loved ones, and then work backwards to decide what is just.
