You had me right up to Jim Crow laws. That is a bit hyperbolic and an inappropriate comparison, IMO.
When you're passing a law that disproportionately affects certain ethnic groups, that particular comparison is apt.
Your ethnicity isn't being discrimated against, just your country's economics circumstances. No reason to bring the SJWing into an economic argument.
Restricting people, no matter their ethnicities, based on their country's circumstances is generally frowned upon. Especially when it only affects citizens of a few countries. "Well, this law only applies to <action> Too bad only people from these countries perform these <actions>"
Besides, your claim that the money is being laundered is highly speculative and unproven. That's the definition of painting with a wide brush - because most money is suspect, you cut off access to all of it?
Local residents and voters have the right to keep others out if their laws allow for it. Outsiders/non-citizens don't get a vote.
This is fundamentally a monetary and trade policy issue.
Are you claiming that, for example, tarriffs on Chinese dumped imports are also equivalent to racially targeted laws?
