I've seen restrictions on a visa waiver compared to preventing green card holders from returning to their homes. Here I'm seeing total admission to the country if you can get here compared to banning people who already have visas and have completed the extreme vetting required. I know people who have to fly back to their home country yearly as part of the process of maintaining their visa, and live in fear it won't be approved. And they aren't even from the mid-east, where the standards are harsher. It's not a fair comparison.
