Now Indian Student can't work in UK after studies

I was just reading on internet and found this and I think its worth sharing here. I know lots of people are planning to study in UK and I know many who are already doing it.

A facility that allowed Indian students to work here for two years after their courses are over will be closed from Friday as part of the Cameron government's drive to cut migration, which may put-off those aspiring to study in the UK.
Under the Tier 1 (Post-study work) route, Indian and other non-EU students were able to take up work for two years here after the completion of their university courses.
This route will be closed from Friday, the Home Office has announced.
The facility was popular among self-financing Indian students who sought to recover some of the expenses of studying here by working for two years.

What do you think, what will be its positive and negative effects ?
