We eat far more meat now at a time when far far fewer people are personally slaughtering animals than ever before in human history, so I think the claim checks out.
People who kill animals themselves regularly are probably subsistence farmers who consider meat a luxury, and what's more, the way they killed them was probably nothing like the incredibly high volume processing that goes on in a modern slaughterhouse.
I definitely think that if most people had to visit a modern factory farm and see the life cycle of one of these animals, kill it and process it, they would probably be shocked at what is legal.
