Cheap labor for the Israelis, and high import taxes to Gaza via 2 tax ports before anything reaches Gaza.
Win win for the Israelis.
Israel already has more than enough cheap labor, hundreds of thousands laborers from South-East Asia, the Phillipines etc, Israel can have half of Africa if it wanted to. It's win-win for the Palestinians but it's not what it's all about is it? For self-proclaimed pro-Palestinian supporters it's all about the elimination of Israel and nothing else.
