It should be a combined effort of government regulation through fining, legislated rules, penal tax programs and other aspects of the "hard" power tool kit that the government at the municipal, state and federal levels has and often uses.

but it has to be a joint effort of government and social involvement. The people themselves have to be directly and proactively involved through awareness/advocacy, appropriate boycotts/protests, and a collective shift in consumer habits/preferences.

This is what changed the sweatshop mentality and business practices of Forever21 here in LA, where the women laborers had to boycott, picket and strike for two years and inevitably at to file a federal lawsuit. The combined effort of workers putting pressure on the business, on growing public awareness and consumer patterns shifting away from support exploitative practices, and the threat of direct government force all pushed and pulled Forever21 into a more equitable business model, which benefits the workers, the customers, and in the precedent the society as a whole :)

But are you suggesting to crack down on businesses that employ illegal immigrants, or only on businesses that pay below minimum wage, allow unsafe work conditions, etc?

both.

They'll do it once, they'll do it again
The world is run by businessmen

He takes your money, you take his word
He tells you things you've never heard
He says "Sign here on the dotted line"
But you don't understand, no you don't understand
But you think it's alright

When she said "semi- evil" she was probably refering to all those scary desert people;like in "The Hills have eyes".
