Anyone who has studied any taxation laws knows that it is a slippery slope and the more taxes, the more laws, the more exceptions, the more inclusions - all in an effort to make everything "fair".
In Australia, one example is the Medicare Levy Surcharge. Australia has a reasonably good free health system, but a single person who earns over A$50k annually is "encouraged" to have private medical cover also. If they don't have private medical cover, they have to pay and extra 1% of their next income in tax. This is on top of the already 1.5% Medicare Levy that has to be paid - oh, except if you were exempt from that also (for various reasons). Yes, you can still use the free health care, but you have already paid either 2.5% of your income, or 1.5% of your income plus private medical insurance that you are not using, for the privilage of using the "free" care.
An example of money-for-nothing is the single mother at home with three kids. She receives a weekly income for each of those kids, including subsidised healthcare costs (pills, bills, etc) on things that aren't already free, subsidised public transport costs and others. Not saying it is a good life, but it is money/subsidies that I would never be entitled to. It doesn't take too many calcuations to work out that some people who don't work are financially better off than someone on minimum wage.
Trying to argue which taxation system works worldwide is fairly pointless as all countries are very different in their requirements of government. Ask yourself why Hong Kong doesn't have (or need?) a GST/VAT, but most major economic countries deem it necessary to having a robust and effective taxation system.
