I have written before about the ethics of boycotting settlement businesses that employ Palestinians.
Data from a recent UNCTAD report ought to give advocates of such boycotts pause:
In 2015, nearly 12 per cent of employed Palestinians worked in Israel and in settlements . . . Employment in Israel and Israeli settlements accounted for 16 per cent of the employed population in the West Bank . . . Without the employment in Israel and Israeli settlements, unemployment in the West Bank would be in the range of 35 per cent, a rate as high as that in Gaza. (pp. 2-3)
