No you don't understand. When they cross illegally it means they are going to hide all their lives, without any access to any kind of aid, medical assistance or education even for their children. It's generations and generations of people who will be eternal prey for anyone who want to exploit them. They will be and remain poor, without identity neither nationality for their children, who under such circumstances will never come to love their new country. They will never be heard because they will never have the right to vote, which also means that their situation will never change. The only change for them would be to lose everything again when they are found and deported. That's why they will remain in hiding and silent. It's a vicious circle. I'm French and I am an immigrant in an Asian country. Here they only accept a few immigrants but they totally take them in charge. They have full programs to learn the language while getting a training and also working part time to finance their living. At the end you get the qualification, a Visa sponsorship, a job and a place to live. They make sure that immigrants don't end homeless in the street and in fact yes I have never seen foreigners begging with their children in the streets like I saw so many in France. People like to criticize Japan but at least they don't boast everywhere that they will accept everyone and help everyone... just to open them their streets to beg or sell their bodies and that's all. You advocate for more legal immigration. I say the whole system has to be completely destroyed and rebuilt so that you don't end AGAIN with an hidden population of poor and disadvantaged people who will just stay that way all their and all their children's lives.
