Not because I think that his thoughts are necessarily the solution but because the lack of constructive criticism.
First of all I didn't read the post to say "this is to solution to end all solutions" but rather here is an idea could it work.
Second how is this a top down approach in any classical sense? His claims is that the companies who think they can create jobs with more money, exist out there and he want the find a mechanism to find them instead of simply distributing at large across the system and see what happens.
Third the US is probably the best country in the world to be an entrepreneur and business. There is very little in the way for anyone to find a need and then go out and build a business around it and there is a huge market for that. If your claim is that it can only be solved by making that part easier then the entire premise of capitalism seems flawed (I don't believe it is and I am not saying you are claiming that either)
The problem fundamentally is that you can only adjust your metrics so far before they become meaningless.
The first step to get the US out of their debt is to raise taxes. That won't make the startup environment better but it will start showing that the US as a country are ready to pay their bills instead of speculating their way out of it.
And before you start calling me a socialist and other nasty things let me just pre-empt this by the following.
I live in Denmark, a country with a progressive tax system +55% tax for the highest incomes and a sales tax of 25%. A car here cost 3 times the amount of a car in the US all because of taxes.
I am a member of the only liberal (in the european sense) political party and is fighting to get lower taxes.
So I am not saying raise taxes lightly. I am simply saying that the US have reached a point where the low tax is working against them not for them.
All systems have thresholds especially economic ones. To keep wanting more of the same ends up creating a self sustaining effect after you reach a certain point. The US have reached that now.
