Can't address the content, eh? What does the CRS care about the tax system we have? And they don't make up the burden tables.
It's not that I can't but that there is no need to since the bias in the piece is obvious.
And, yes, the JCT, CRS, CBO, and other similar groups have a VERY large vested interested (as do you apparently) in retaining the existing suystem. And yes, the tax burden tables developed by these groups are highly misleading and are one of the reasons that we have arrived in the present tax mess we're now in. Congress thinks such tables are meaningful when in fact they are just the opposite.
Apparently you can't/won't see that because of your own bias.
So what have you been addressing for the last two hours? The definition of excise tax and sales tax. Yeah, that's a lot of content.
