As a taxpayer-funded scientist I publish all of my stuff on arXiv before submitting it to a journal, and it is 100% worthless for my career. If my research is not published in respected journals, other researchers will not bother looking at it, and justly so. Have you tried reading a paper selected at random on arXiv? You'll spend many long hours reading it only to end up realizing that it's garbage (unless you're lucky to realize this from reading the abstract).
