Here in Spain interns earn 0/month, and contracted workers earn 700-900/month working from 9A.M. to 19A.M. This salary for contracted workers are offered in important companies too.
And in some companies interns work from 6 months, and when they end, they are contracted again in the same company as intern for other 6 months, giving the false hope to get contracted some day, so they have a worker from 1 year with 0 cost.
Also in other companies, you are contracted for a 4h part-time work, and they compel to make 4 more extra hours every day not rewarded. If you don't do this 4 not payed extra hours, guess what happen...
So, as I don't have businnes heroes in my country, I will name "Silicon Valley" and the way they do businnes as my heroes.
