This was far, far less common before they started charging for checked bags. Once they made that an upsell opportunity, people started behaving in exactly the way airline policies encouraged.

The other big reason is the airlines choosing to ignore baggage theft. I had a bag stolen out of SFO and they tried to first disclaim responsibility and then offered to reimburse it at like $2/pound, which again means that they’re giving customers a financial incentive to carry everything into the cabin.
