It's true, but the point they were making in that, it stings to lose half, is still there none the less. Tax sucks and when you see what you could have earned if it wasn't for tax, it sucks.If you earn two billion and the get taxed half of that then I'm pretty sure you can survive on the one billion left over. And your tax can maybe go to help the society and staff that has helped earn you it in the first place.
The better mentality is to think of income tax like vat. It's never yours. The price of your wage is the amount without tax, and they add the income tax on to be paid by the employer through your wage, and if there was no income tax, you'd get paid 20 percent or whatever less, but still it sucks.
