Most of these 10 items aren't "corporate welfare." Oil depletion allowances for oil companies are and I think they are obsolete. They should be eliminated. It appears the people who put these lists together have a poor understanding of how things actually work. A few simple explanations.
1. All wages and salaries are excluded from company taxation just as are all company expenses. Corporate taxes are paid on net profits.
2. Corporate jets would be considered depreciable assets. They are no different than any other company asset. Maintenance, fuel, pilot salaries and everything else related to the airplanes are expenses. See 1 above. Executives are expensive enough that large corporations consider the time savings involved in providing private air travel is worth it. You can criticize that, if you like, but you can't call it corporate welfare.
3. As I said above, the oil depletion allowances are indeed corporate welfare and are obsolete in my view.
4. Drug company profits are earned. They aren't welfare. If you think medicare/medicaid should get better prices and they can't because of a corrupt law, talk to your legislators to see about changing the law. You can't blame the drug companies for seeking advantages. You can blame the government on this one. Finally, if you think the government should not be involved in taxpayer funded drug research you should talk to those same legislators. I don't think the government has any business funding private research. But this isn't corporate welfare.
5. The purpose of capital gains tax rates is to provide incentive for people to invest in business. It applies to everyone, not just corporations, so it isn't corporate welfare either. Tax rates are determined in Congress. That is the place to go to end capital gains rates if you disagree with it. I disagree with it just like the author, but I don't blame business for it.
6. Most of these tax reductions occurred because the state was competing with other states for the location of some asset like a factory which they wanted in their state to add jobs. The companies negotiated benefits for locating in the state. Reduced taxes aren't corporate welfare either. They are reduced taxes. One assumes the state would make up the tax reduction from taxing the employees of the factory over time. It's business, not corporate welfare.
7. I'll accept farm subsidies as welfare of sorts and I don't think the government should provide them. The reason it does, is because governments in other countries subsidize agriculture and the subsidies help keep American farms competitive. The issue is whether or not it is corporate welfare since it apples to family farms as well. It applies to all farms. Even I, who is not a farmer, have received subsidies to convert a corn field to a hay field. The funds were provided under a law that allows this type of subsidy as soil conservation. Something we shouldn't do? I agree with that but, again, it isn't corporate welfare.
8. I'm completely against this practice. I view these banks as too large to succeed. The purpose is to avoid a potential bankruptcy that would seriously hurt the FDIC. Perhaps the FDIC shouldn't exist either. The government should treat all people and all companies equally. It should never play favorite. Nevertheless, it isn't corporate welfare either. It is a loss of revenue in the same way a tax reduction is.
9. The portfolio is a loan portfolio. These are loans to companies, not payments to companies. They are repaid with interest. I agree that government should not be in the business of loaning money but there is no way to justify calling it corporate welfare. Loans like Solyndra fit the same situation. Government shouldn't be in the lending business. I'm happier without the EX-Im bank too as I am much of government. But it isn't corporate welfare.
10. This is ridiculous. The government contracts with companies to buy things that it needs. It is a purchase, not welfare.
So there you have it. 1 out of 10 is actually corporate welfare. Many of these these comments point out corruption in our bloated government and many of them should be curtailed or eliminated. I don't argue that. But this a nonsensical list put together by a partisan blog and has no relation to real life.
