According to the Palestinian Central Bureau of Statistics, already some 110,000 Palestinians work in Israel and in Jewish towns in Judea and Samaria.
The average daily wage for a Palestinian in Israel is NIS 196.4, well over double the to NIS 94.2 average wage for for those in the West Bank.
This means that about 25% of all income in the West Bank comes from people working for Israelis. The daily wage for employees of Israelis has been steadily increasing through the years while the number of hours worked per week has been decreasing.
Now, picture the impact on the Palestinian economy if BDSers had their way and all Israeli services were boycotted. Or if a Palestinian state was established where going to work would entail crossing an international border.
