I support the move, simply because I am sure these companies are abusing the spirit of H1B. But I really, really doubt if this is going to improve labor conditions or US economy by any meaningful margin. The end goal has not been clarified, and that is leading to confusion among both H1B people and US citizens. H1B visa holders already lead uncertain lives, and this is adding to the stress. Citizens who are not super well-informed are looking at all brown people as people who are taking away their jobs, and even worse, as recipients of US charity.
