Washington Post’s (April 15) carries an article under the title, “Hillary Clinton sounded a little like Elizabeth Warren in 2008, too” accompanied with the following lead copy.
“Hillary Clinton's announcement video Sunday included a clear-as-day shout-out to Elizabeth Warren. "The deck is stacked" against average Americans, Clinton argued, echoing Warren's "System is rigged" mantra.” From The Washington Post.
AP Radio News (April 13) also reported that:
"The former First lady, Senator and Secretary of State jumped into the race in an online video. She wants to be the champion of average American, adding "the deck is still stacked in favor of those of the top."
What does "The deck is stacked (against average Americans / in favor of those of the top)” mean? Could you paraphrase it in plain words?
