That is simply not true. You don't even have to look too far in the past to see examples of meaningful differences even if you restrict yourself to economic/financial/business issues. The most recent example is the internet privacy repeal bill. But even Obama's term alone saw Dodd-Frank, the auto bailout, the stimulus package following the great recession all supported by Democrats and opposed by Republicans. The two parties are nowhere near the same on economic issues. Yes, they are both largely in favour of free trade. But there are very significant differences in terms of philosophies the two parties take towards regulatory behaviour.
