You say give a lot of money to rich people but really it is let rich people keep more of their money. The idea that they will make more investments if they have more capital is flawed because the rich never lack for capital to invest in promising projects. Actually taxing the rich to invest in infrastructure in the end actually can be just a beneficial to the rich as letting them keep their money. The rich benefit greatly from the commons, the publicly financed infrastructure not just the resulting infrastructure but the spending to create that infrastructure.
Trickle down is weak because it is just a trickle. Money flows up to the rich much faster than it trickles down to the less well off. Money flowing to the rich is a gusher, but the trickle down is just that, just a trickle. Every penny you give to the poor ends up in a rich person's pocket.
Please don't take my comments as negative. I am just adding my reinforcement and insights. I think this is a wonderful presentation and no I will not probably listen to the podcast. I am a fan of the written word. I prefer text to audio or video especially regarding the spoken word.
