Why yes I do, roughly. We take in around 3 trillion and spend about 3.5 trillion. And even doubling our effective corporate income wouldn't even match the proposed 700B defense budget, besides putting a possibly unrecoverable damper on medium to small business. Around half our income comes from individual taxes, and when you start taking bigger bites out of payroll taxes, it's the labor force that really pays it, essentially a double whammy for the workforce.
So yes, while raising revenues is obviously central to providing every citizen with unlimited health care, taxation alone cannot bear the burden. 
So my suggestions stand. Modify entitlements as humanely and gradually as possible, and rethink our role as the world's policeman.
