Your Wikipedia tripe says this right in the beginning:

"To meet Wikipedia's quality standards, this article or section may require cleanup."

"Thus, many interpret the caste system in accordance with karma, as those with good deeds are born into a highly spiritual family (probably the brahmana caste)."

Thats the personal opinion of the author (and we dont even know who he/she is). "Many interpret" (they do so wrongly). Many who? Do any religious scriptures say that? They dont. Cast in classical Hinduism wasn't accorded birth but by profession. So you cant be born into a cast. Not according to Hinduism.

Secondly:
Shaivites are a sect within Hinduism any there are many.

"...[M]ost Hindus believe in universal salvation: that all souls will eventually obtain moksha, even if it is after millions of rebirths."

Yes. It means there is no eternal damnation for any living being no matter how evil. They will still attain salvation no matter how long it takes.

You are going to have to do better than picking up some tripe from Wikipedia.

"The servant class, the Shudra, serves the higher three classes. They are not allowed to read or hear the Vedas, but they are allowed to participate in Bhakti Marga, the path of devotion. It may seem degrading to keep them away from the religious texts that at the same time are keeping them from raising their station in this lifetime, but as a Hindu, they were placed in that class for a reason. Karma, which follows you throughout your many lifetimes, determines which class you will be in for any given lifetime. You may be demoted to an animal, reallocated within the class structure, or even elevated to a deity. Your actions in each lifetime affect your karma, and if a Shudra does his dharma it will have a positive effect on his/her karma, perhaps elevating him/her into a class in which he/she will be allowed to study the Vedas and progress along his/her spiritual path."

... After death. And only in the next life.

“Since it is accepted that one’s caste is determined by one’s past karma, there is no reason to be bitter about one’s lot or envy others”
~Ludwig, Theodore M. The Sacred Paths: Understanding the Religions of the World.

And no reason to help the poor escape the consequences of their bad karma.
