doesn't sound as though he is claiming that you can't take credit for building a business, just that you can't take all the credit. Yes, he's saying you can't take all the credit, which means that you can't "take credit" for it. Taking credit has an implied "all the", as in, "take [all the] credit." This distinction actually matters. Obama is taking something absolute -- This is my business, these are my profits -- and turning it into something vague. That vagueness leaves plenty of room for all kinds of government controls and taxes. In fact, contra Obama, if you built a business, it is rightly your business, along with all of the profits (and all of the credit).
