Why is asbestos removal a controversy?

Removing asbestos is very expensive because the substance is so dangerous. Anyone who removes asbestos has to be properly trained and certified, bringing up the cost. On top of that, a lot of special equipment is needed for the job. Because it's so expensive, but so necessary in some cases, it can get a little bit controversial. People have to choose between paying high fees, or putting themselves in danger of developing cancer later in life.
