Our corporate tax rates are the highest in the world, and that only happened recently (Japan's used to be higher, but they wised up.)
Now I'm sure you will retort that companies don't pay the actual tax rates - they get tax exemptions, subsidies, and so forth. This is true only if they are chosen to get those exemptions or subsidies. Plenty of businesses arent getting any of either. Plenty of businesses in the United States pay the highest corporate tax rates in the world with no exemptions or subsidies to easy the harm done to them.
Now, while you were reaching for the exemption and subsidy card did you notice that you skipped over part of the problem? There are two problems. One of them is those exemptions and subsidies, and the other is that without them its the highest corporate tax rates in the world. The industries that can capitalize on those exemptions and subsidies can compete in the global market, whereas the industries that are unable to capitalize on them are not only at a disadvantage on a global level but also on the local level because foreign competitors can easily drive them into oblivion.
It is the complete ignorance of whats going on that is part of the problem. We have this debate about taxes and regulation and some fool going off saying that taxes are down. Taxes arent down at all. You would know not to say such ignorant things if you werent so ignorant that you didnt know that America has the highest corporate tax rates in the world. A problem of course is that the statement "taxes are down" can later be justified by reaching for actual truths, but you arent knowledgeable enough to have led off with the truth itself. You just know that somehow there is a grain of truth to the statement.
You cannot rationally debate about the consequences of inaction nor can you debate about the consequences of proposed solutions if you arent leading off with the truth itself. You need to discuss whats actually happening, rather than bullshit hyperbole like "taxes are down", in order to discuss these things rationally.
