It's clear that many of the groups behind euthanasia legalization simply want to establish a legal system of killing the aged, the dying, the disabled, for the purpose of relieving society of the financial burdens of caring for these folks. It is a similar motivation with the abortion pushers. The racist eugenics agenda of Planned Parenthood is well known, and I can't count how many times pro-aborts have justified abortion by claiming material benefits to society. It's vile.
I believe you're right.
