It's a slippery slope as to whom you disenfranchised to redistributed that cash: but it will inevitably be a large group of people in the middle, not the minority elite you sold the policy on. If some people can't accumulate something they can't do bigger things as creators or create bigger markets as consumers.
You won't disenfranchise anyone, because the investment will more than pay for itself. That's the point. It's just another form of seed funding for ambitious start-ups. And $30bn/yr is absolutely trivial compared to the opportunity costs of an economy geared more to financialisation and regressive wealth extraction than to productive engineering and invention.
This silly proposal is nothing more than socialized venture capital. We have real venture capital who invest in “far fetched” ideas already — and they have willing participants who know what they are getting into — not people being forced, literally at the point of a gun, through taxes.
