Glenn Beck is acting as if Progressives would naturally be anti-business, but the movement, even the modern movement, is based on improving business conditions. Of course other areas too, but it has a big focus on people's jobs because that's where they spend their time.
It started out to address the concerns of the left while also standing against socialist ideas. You could say it's like the Open Source movement that saw the Free Software movement as a little too anti-business and wanted to pursue a similar agenda while not coming out too hard against business as usual.
Conservatives and Progressive have a lot more in common that I could get into here, but that's not the point. It's that Glenn Beck knows a lot of Democrats are pro business and pro tech and acts as if he doesn't understand how it could be possible. He's just playing dumb.
The whole Progressive movement is based on the philosophy of improving business conditions by balancing power. It sees conflicts coming from monopolies and consolidations of power and tries to minimize those through strategic government intervention. Lots of people believe in small businesses but think that some government intervention is needed to allow them to compete. Theodore Roosevelt considered himself a Progressive Conservative. I can easily accept that Glenn Beck doesn't think that this kind of intervention is effective, but I can't believe he isn't even aware that this opinion exists when he spends every day of his life talking about it.
Maybe he's just pretending not to understand to relate to his audience who generally like straw man arguments. Maybe it's a brilliant strategy to slowly introduce people to the idea that the other side might have some things in common with them. If it is, I hope it works.
