You won't "save our country" by attacking the millions of individual citizens you call "the rich". The enemies of our Republic are individuals, not groups or classes of taxpayers. Groups and classes were defined by Marx. Individual rights and Liberty were defined by the Constitution.
The main thrust for open borders comes from higher income tax payer who want cheap labor and or Democratic party control. They have vastly greater control over things then you and I do. Marx wrote that the capitalist
“would sell the rope to their own hanging and the Republican branch of the elite have proven this to be true. Not that they will bring communist to power but that a wealthy group of mainly elite Democrats with rino Republicans allied will take over the country and destroy liberty and individual rights. These upper class Democrats are the source of the problem along with the institutions they control. If they were not wealthy and did not have control of the institutions that they have and if their Republican counter parts were not so feckless we would not have a problem. The main problem does come from these upper classes and they do need to be called out.
