I don't see the choice between being Lady Bountiful or not as being a left vs right issue; nor is understanding one needs control of one's borders in order to achieve a better place without being swamped by those wanting a share of your achievement, thus destroying your efforts to improve your part of the world.
Whether someone who supports letting folk in is willing to house those they would allow is a reasonable consideration. It indicates how genuine they hold their expressed opinion. Not worth dwelling on though.
Of course improving their homeland so they don't want to leave is best, but that's too costly to fo short term, and circumstances tend to ensure investment/charity is likely to be misused, either to make the powerful richer, or to wage conflict. The only option there is they clean up their act (as a nation rather than individuals) treat each other with respect, and allow mutually beneficial commerce/industry to speculate in whatever the nation has good potential to offer.
