That doesn't really work, because countries are set-up so differently. There are countries without any taxation, usually due to natural resources. Others do not have a formal form of taxation, but demand other forms of payment from their citizens (I very much recommend CGP Grey's excellent video "Rules for Rulers"). Then there are countries that highly tax individuals, but provide great benefits. Take Europe. Of course you have people who disagree with high levels of taxation, but many are happy with high taxation levels because they do not have to pay any extra money for child care, education, and health care and there are societal benefits to taxes acting as an equaliser. So depending on the country, different levels of taxation make sense. The same can't really be said about multinational corporations, since they operate on a _multinational_ level, it makes sense to have rules that apply globally.
