Why would you compare total cost of living to find which country has the higher taxes? It doesn't make sense. Besides, you claimed Denmark had higher taxes. It has been proven that it was wrong.

>Tax burden is just leverage to help companies and harm workers.

I would like to hear how you reached this conclusion.

>just because it's a tax in Autralia you can't simply count it as a tax in Germany.

Yes you can, if your goal is to make a fair comparison between countries. The OECD uses it for measuring the tax burden on income. Especially because, the countries like Germany use 'creative labelling' to hide how much money they collect each year.

>Because the pension contributions are used for non-insurance benefits that should actually be paid for by all taxpayers, such as the mothers' pension or the equalization of pensions for retirees in East and West Germany. BTW "every year billions from the tax revenue is used to pay the pensions" proves social security and pension contributions aren't taxes. Tax money is a subsidy not the main source.

You've just proven my point. Because the money can be easily shuffled around, in practice, it is no different than income tax.
