RonBee, thank you
of course I should first think about the reader too .i shouldn't confuse them or tell them something "may be an opinion" as a certain fact
but because I do believe that the percentage of the japanese workforce in japan is higher than bahraini workforce in my country.. and I said :
the workforce of Japan in their economy is largely native, because the locals have the priority in their economy.
isn't fair enough!! if they don't have the priority !! why don't they employ foreigners such as indians!! moreover they accept lower wage!
when I said priority I didn't mean :) discrimination , in fact I mean it in a positive way ,that they have the priority !! I can't see any wrong :)
so next time I try to talk in general

based on certain informations
thank you a lot for Your advice
