At this point: almost no one. The super majority of manufacturers and distributers of asbestos products have gone bankrupt. Kaiser Gypsum was one of the last solvent companies involved in a lot of asbestos litigation and they filed for bankruptcy a few years ago. Bankrupted companies of this kind generally establish trust funds for claims related to asbestos products, but those funds pay out paltry amounts. There are a few other large solvent companies though, so it depends on what caused the likely exposure. If, like many people, a person got asbestosis or mesothelioma while in the armed services, they are SOL because the VA pays squat.
