Its not about fighting against walls, we all constantly create walls (imaginary and real, conscious and unconscious) we need to understand the basic reason for such an act ;
why are the American’s so scared ?
How can we change this immigration into something positive by changing our attitude and helping countries where populations are suffering ? (all the money spent for security and building walls could be invested in these under-developed countries- by making a pact with the governments_ we give you funds-help, employ YOUR people) until and unless we dont understand that when a Mexican, a Chinese or an African dies due to ill-treatment or mal-nutrition, we have murdered one of our OWN Human family !
and until and unless we dont abuse these cheap markets and "cheap" man-power, these murders shall continue !!!
How can we stop this in our neighbourhood ? in our city ? in our country ? may be its time to look back and understand that individualism is good for progress of self but for the progress of the society , we have to change !!
