First, good luck finding Haredi (ultra-orthodox) construction workers (why do manual labor when you can get paid by the Israeli government to defend Israel through the important work of studying in a yeshiva). Second, anyway, even if you can find Israeli Jewish (secular or religious ) construction workers, they are more than likely to cost you greater than 16.6 % more than would the ever-plentiful Palestinian or foreign (Chinese usually in the construction industry) workers.
So, now, Palestinians and Chinese will still build your home for you, or the Thai workers will pick your crops, but you can feel Halachically 'kosher' about doing it. You got a valid coupon from god to do it.
