[Attack on Titan] Why is Marley so short-sighted?

Throughout AoT, Marley is shown to absolutely hate Eldia, to the point they shoot themselves in the foot multiple times out of sheer discriminatory hatred. For example, they often treat Eldians as lesser, even Titan Shifters, people who can heal from basically any injury and turn into giant monsters who can in some cases destroy entire nations. They also force Eldians to fight for them on the front lines, which obviously means the race they treat so badly now has extensive combat experience, and as we see in one of the latest chapters, the Eldians in the Marleyan military outnumber the Marleyans. Marley is also arguably entirely to blame for the Rumbling, as they attacked Paradis knowing full well that Eren Jaegar hsa control of the Coordinate, and even though he may not be of royal blood, there are people of royal blood on the Island who he could simply touch to basically end the world. So why in all of this time don't they ever take a look at the long-term consequences of subjugating the Eldians so much? Is it simply blind arrogance?

There's definitely more emotion than logic to their hatred of the Eldians.  They hate them because they're terrified of them, and it's not surprising they fear people who can turn into the monsters that causes so much terror and death.  But it's ultimately hypocritical, because they abuse the power of the Titans the same way the Eldian empire did.  

In the "loading screens" (I don't know what you'd call them in an anime), Marley is described as a military dictatorship.  Many dictatorships on Earth control their people through fear of the other, and through a belief that the government can protect them from the same.  So in a way, it's in their interest that the Eldians remain a low-key threat in the minds of their people.
