It makes me wonder whether an income threshold makes more sense as a dividing line than hourly vs. salaried. Higher salary equals more specialized knowledge equals higher risk to employers when those employees move to a competitor with trade secrets in their head (or equals higher value of those trade secrets). Hourly vs. salaried is often correlated to pay scale, but imperfectly, and it does seem like specialization / economic value of knowledge is really what they're trying to get at with the split in this bill.
