I would disagree, there is no institutional discrimination in first world countries at the current time.
There is a class discrimination. Look at all the cases SJWs and all the other liberals keep talking about whether pull overs or shooting unarmed people or etc.
Compare it between black areas and white areas and then between lower class areas and middle or upper class areas and you'll see that these things happen generally more in poorer areas regardless of race or gender.
The thing is that makes the US stands out in the industrialized world is that the US was late to end discrimination policies between races thus black people have many of them being poor, while in other countries there proportions between classes is pretty much the same as white people since they had time to redistribute among classes.
If you live in a normal lower-middle class area for example, you're less likely to be pulled over or arrested or shot than if you lived in a ghetto. Regardless of your race.
There is an important term to describe race relations in the US., De facto. when a certain race relation is enshrined in law it is de jure. Segregation in the Jim Crow south was de jure. De facto is when something is in effect true whether or not it's specifically put in law. In many school districts in the US for instance you have de facto segregation because of the way our school zones are organized and funded. Some schools are almost entirely white or entirely african american and predominantly minority schools have lower funding since the bulk of the funding from our public school system is from local property taxes.
De Facto vs De Jure is a way to point out that just because Uncle Sam doesn't lay out laws that specifically target minorities doesn't mean that they don't in effect hurt those communities. An instance of this is the war on drugs, which aids to Nixon actually stated after the fact was a way to target black and hippie communities that were seen as enemy's of the administration.
Now to your point about economic discrimination. This isn't an unfair point, but there is the question of cause and effect here. I would allege that things like the war on drugs, which puts huge numbers of african american men in prison and seperates them from their families hurts those communities economically. As does the US justice systems propensity to levy huge financial costs. We have in place networks of laws that make it impossible for these communities as a whole to drag themselves out of poverty because there schools are worse than average, they are disproportionatly jailed, they find it harder to get a job (experiments have been done that show that identical resumes with only the name changed to a sterotypically white or black name have very different call back rates to the detriment of blacks), etc. etc.
How can you say that all of this is because they are poor and not that because of these laws they are poor?
My dream is a hemispheric common market, with open trade and open borders.
