especially because the creation of the "Welfare State" was the first Muslim Caliphate that was based entirely on the Prophet's teachings and Quran (he had just died). This welfare state lasted centuries so it disproves the myth that conservatives repeat over and over, that a "welfare state" is unsustainable. Clearly it was and is sustainable to devote tax to alleviating poverty and making income and wealth equal for all citizensThat's PRECISELY why they complain about Islam.
White people fear Arabs and Muslims the most over history as a group/religion/society, this goes back to Europe. It's partially because Arabs/Muslims are the only group that Euros came in contact whose culture, language, religion...they were not able to crush. One on one they fear black people more, but as a group/society it's Arabs/Muslims. Also because it's the only other group that is still culturally and religiously expansionnist in a way today (as opposed to China for example, that doesn't care about cultural/religious expansion).
In other words, they complain about Islam because they understand that it's a powerful religion/culture/political entity that they cannot control and that does not fit in the western liberal capitalist/liberal framework.
In his time, equality was extended to all citizens, even to the caliph himself, as Umar believed that "no one, no matter how important, should live in a way that would distinguish him from the rest of the people."
Limitations on wealth were also set for governors and officials, who would often be "dismissed if they showed any outward signs of pride or wealth which might distinguish them from the people." This was an early attempt at erasing "class distinctions which might inevitably lead to conflict." Umar also made sure that the public treasury was not wasted on "unnecessary luxuries" as he believed that "the money would be better spent if it went towards the welfare of the people rather than towards lifeless bricks."
Umar's innovative welfare reforms during the Rashidun Caliphate included the introduction of social security. This included unemployment insurance, which did not appear in the Western world until the 19th century. In the Rashidun Caliphate, whenever citizens were injured or lost their ability to work, it became the state's responsibility to make sure that their minimum needs were met, with the unemployed and their families receiving an allowance from the public treasury.[2] Retirement pensions were provided to elderly people,[1] who had retired and could "count on receiving a stipend from the public treasury." Babies who were abandoned were also taken care of, with one hundred dirhams spent annually on each orphan’s development. Umar also introduced the concept of public trusteeship and public ownership when he implemented the Waqf, or charitable trust, system, which transferred "wealth from the individual or the few to a social collective ownership," in order to provide "services to the community at large."
During the great famine of 18 AH (638 CE), Umar introduced further reforms, such as the introduction of food rationing using coupons, which were given to those in need and could be exchanged for wheat and flour. Another innovative concept that was introduced was that of a poverty threshold, with efforts made to ensure a minimum standard of living, making sure that no citizen across the empire would suffer from hunger. In order to determine the poverty line, Umar ordered an experiment to test how many seers of flour would be required to feed a person for a month. He found that 25 seers of flour could feed 30 people, and so he concluded that 50 seers of flour would be sufficient to feed a person for a month. As a result, he ordered that the poor each receive a food ration of fifty seers of flour per month.
