The bodyshops like TCS, CTS and Infy will suffer, though. Their exorbitant margins on shipping obedient and freshfaced barely-post-teenagers off to projects where they're mostly expected to punch the clock and do bits and pieces of what the Architect says / tech support are over. They'll survive, though - the Leads, Pricipals and Architects will just have to travel up and down a bit more. I expect they'll lay off a lot of people, though. And the long tail of salaries here will likely go down. But if there is an increase in off-site outsourcing, it'll balance things out. They'll just staff more people at the home base and freeze salary hikes citing this.
Dowries will also likely go down. There's going to be a sudden dearth of grooms with the cachet of foreign work experience and a cache of saved dollars. It's also possible that if this sticks a lot of the shady engineering colleges that have sprung up here like weeds will see reduced demand. Entry fees at medical colleges will probably spike.
