Which benefits have been cut in the US in past ten years? Be specific. I won't count things that were cut to be replaced with something else bigger, like Obamacare.

There's a few politicians appealing to the people who'd like to see some things trimmed, but they haven't done anything significant about it in a decade or more. This is a part of the reason you're seeing Trump's level of success, the perception by these people that they keep trying send people to DC to cut things down, who then make a big show of resisting while not actually resisting.
