"On one hand, H1B holders can be paid below market rates because it is very hard for them to switch jobs. For this reason, they create resentment from American citizens."

This directly lowers the wage an American can earn. This is one way corporations pin the market to a wage they want rather than what is reasonable and fair for the worker. "That's the market rate" Is some serious bullshit, they manipulate it at every turn.
