You underestimate the reality of some "modern jobs" out there. There are garment workers in Bangladesh locked inside factories so we can enjoy cheap clothing. There are miners in the Congo working under militia control. There are migrant laborers in Gulf states with their passports seized, forced to work 12 hour shifts every day.
Some modern jobs absolutely contain elements of coercion, abuse, and exploitation that are comparable to forms of slavery.

I think the point should not be to do away with the term nor water it down but to fight the offending elements across the board.
