What's still happening is the Islamic slave trade within and outside Africa.

The Middle East had market economies thousands of years before Europe was discovered. Literally.

Up until the 16th century when Portugal and Spain started hopping on ships to sail abroad to trade, the hub of world trade was the Middle East extending all the way to East Asia. Other than Sicily and the Iberian Peninsula, Europe was a place of illiterates living in mud huts. They didn't call it the Dark Ages because people went to tanning salons a lot.

A lot of people think that the reason why there were walls built around Jewish settlements in Europe was to prevent them from mixing with Europeans. But it was actually to protect them for getting extirpated by the local populace, as basically the only people who understood market economy for ages in Europe were Jews, having originated from such culture in the Middle East.

That's why Jews were never totally wiped out in Europe, because kings protected them since they were good for the economy. Or rather, they were the economy. I mean, economy past simple barter. There's only so much economic development can be accomplished with a side of beef exchanged for a barrel of wheat, which is what Europe would still be doing today if it wasn't for the East.

Even Berbers, who at first glance may seem pretty basic nomads wandering the desert, have made a living off of extensive trade routes extending from North Africa southwards for as long as history can remember and beyond.

Islam's old greatness that many Muslims still hope to achieve by taking Europe again, was solely based on having huge territories (and slaves like everyone else ofc). Like, Saudi Arabia's greatness depends on oil monopoly and slavery - if they were to change their minds on those things, they'd have to conquer like mad instead to keep its standard.
The British model (created by Jews as you say) made those things obsolete, where even small countries can have a booming economy based on competition and innovation, and the outside investments that come with that. Islam's ordained hatred for Jews never brought it any good. A hatred so strong that you won't even get inspired economically - on the complete contrary, as prophet Muhammad insisted "Differ from them". It wasn't just a power-game to him, but a culture war as well just like today.

Next step is the return of the American System currently forcing its way via Iran and strategically placed tariff leverage, cos the British one depends on Islam using its model and Communists their similar model, and the UK incl. their alliances don't want these societies to use other systems or become westernized. Both controlled and outdated models give stabile and cheap products ready to be utilized by the west's British system of International dependence

Islam's greatness came from the Silk Road. When the Portuguese saw they can sail down the coast of Africa and to Asia for trade and then the Spanish followed, the Silk Road well, dried up. Up until then, they were the leader in the world economy, culture, the arts, math, sciences... Everything. The only European country that had reading and writing at the time was Spain. Moorish Spain. It's hard to believe, but the rest of Europe didn't even have writing at the time, other than Venice. Literally. Most of Europe lived in huts made out of mud and thatch.

Saudi Arabia's economy is hardly largely dependent on slavery.

I didn't say that the Jews created market economy, I said they were the ones doing it when the rest of Europe did not know how. Market economy was introduced to parts of Europe by the Romans. The British model is the London model and London was established by Rome. Paris was established by Rome. Cologne was established by Rome. The hinterlands, the barbarians, that was Europe, before they were domesticated by Rome.

And no, not even small countries could have booming economies because they never did, well, not until after World War II when Truman decided to remake the world in the face of America. It's not an accident that the only countries that had growing economies happen to be those who followed Portugal and Spain and started ransacking the rest of the planet. Namely, Britain, France, the Netherlands, Germany. Netherlands did not become an economic powerhouse because of the tulip trade. The tulip trade was big, but that's not what put them on the map. Germany did not become an economic powerhouse because of its wienerschnitzel exports. People like champagne, but that's not what made France rich.

Those countries made their money from stealing resources from Africa, Asia, and the Americas. Once they lost those colonies, they lost their economic drivers. Tell people that the Netherlands and Portugal used to be amongst the richest nations in history and see how long it takes for them to stop laughing. The Netherlands, a world power? Spain used to be the mightiest country in the world? It took just four centuries for them to boom and then bust. And if it wasn't for the United States of America, one need just look at Romania before Communism fell to see what Europeans lived like until World War II ended. Mud huts, and if you wanted to go to town, you asked your uncle if you could borrow the donkey. That was most of Europe until the 1950s.

Venice, not Sicily. I'm in the middle of another discussion with the Sicilian about Sicilians at the same time, so....
