IMHO It is always worth working more hours for more pay, even as you increase tax brackets. As was said, you still take home at least 50% (usually much more) of what you earn extra. Of course there are other considerations, like quality of life balance. No point in earning a ton of money if you have no free time to enjoy the extra.
What this Taskmaster character is saying is that you should just suck it up and pay your taxes, no matter how high they are, because the government needs it, and they always use it wisely, so shut up and take it. I honestly didn't know that anyone was that stupid, but he made it clear several times that that is what he appears to believe.
