The artificially high corn prices encouraged by the Corn Laws meant natuiewomng class had to spend the bulk of their income on corn just to survive. Since they had no income. Left over for other purchases, they could not afford manufactured goods. Thus the economical spiral worsened for everyone involved. So the workers would have supported the ending of the Corn Laws.
The beneficiaries of the Corn Laws were the nobility and the other large land holders. Landowners had vested interest in seeing the Corn Laws remain in force. The voting members of parliament had no interest in repeating the Corn Laws. So the landowners supported them.
