If these numbers are correct, the payroll taxes total about 13% higher than American payroll taxes, but if you add in what Americans pay for the health insurance that’s presumably included in one of these taxes, it’s probably fairly similar. 20-30% is a very normal marginal American tax rate, and the VAT is high (looks like it may be lower for certain things), but not ridiculous compared to a lot of American state income taxes (Since the income tax is on income and not just consumption). I’m skeptical of a halving of disposable income, especially for someone moving from somewhere like California.
