You should not experince any sort of prejudice between blue and white and pink and gray collars, being Catholic. I’m sorry you’re feeling that. Perhaps you should look at another parish, if possible.
I will say that historically, Catholics came to this country and had to work their way up from almost no collar. Public schools at the time(19th century) gave immigrants grief and had a Protestant perspective. That was part of the reason Catholic schools were established in the US. To have a child graduate eighth grade was a distinction in an immigrant family! That child stood a chance at a better job, perhaps foreman or a secretarial position. In turn, the children of those children actually went to high school, be it “prepatory” or commercial. This meant a chance at night school college or even daytime college, and/ or a better job at a big company. And so on.
These days, I find a lot of entrepeneurs and eaglepeneurs in Catholic parishes, people who do whatever they do not because they want to wear a white collar and work for a big company, but because they want to own their own business and do what they do best, for what they feel a passion. A lot of these small businesses are very blue collar- and those blue collar people are making a lot more doing the grunt work than the white collar people who pay them.
