(Likened to a bookmaker rigging the odds of a betting to ensure that they win and others lose.) Often used in passive constructions. It just feels like the current system has stacked the odds in favor of the wealthy. When it comes to getting hired, the odds are stacked in favor of those who know how to write a compelling résumé and cover letter.
