I think the lottery system might change soon enough. I also think there are problems with tying an education degree with employment. There are many universities that charge a huge amount for foreign students for an education here knowing there is a chance of employment. People paying literally $200k so they can get the practical training and a chance at a H1B sponsorship. There was a local for-profit university that did this while not properly teaching their students. Once this was found out the students lost their money and opportunity at a job.
