I am not US citizen but visa policy is virtually same for any issuing country. Getting visa (any kind) is privilege not right. Government has full discretionary right to refuse entry to anybody whom is not citizen. Not saying it is fair system but it is what it is. Except full open border policy I don't see how you can fix system.
