Considering that's a large salary in many first-world western-european countries, it's probably only a follow-on consideration (ie, GP-comment's hypothetical striking it rich in Singapore).

Furthermore, at that point, you will most likely be able to shelter your income anyway by putting it into a corporation, and you shouldn't be worried about striking it rich abroad.

It's a standard deduction, not taxable income. Having a salary less than that is only favorable to you as a tax payer.

Once you shelter into a corporation, how do you un-shelter? Assumption being that you do want to spend a little of it. You can pay it yourself via salary, or dividends. However, from income tax perspective it's all income anyways.
