Bill Gates supports a "more progressive" tax policy on the rich, but he thinks proposals targeting high income brackets, like the policy proposed by freshman liberal Rep. Alexandria Ocasio-Cortez, D-N.Y., are missing the point.

Ocasio-Cortez has pushed raising the top marginal tax rate to 70 percent on income over $10 million. The top marginal rate is currently 37 percent. But Microsoft founder Gates, without mentioning Ocasio-Cortez by name, said this kind of approach is "a misfocus. If you focus on that, you're missing the picture."
