It's not really concern, its butthurt at the reality they have to live with each day:

Its the same situation if you check that for UK, Canada, Australia, you name it.
Then you go to a Pakistani run restaurant/grocery, and its called "Indian" or "Pakistani-Indian" or some cringey variant of that most of the time. Affirmation of where muh-izzat ends and basic livelihood reality sense begins.
PDF is just a little easy-come easy go echo chamber for bulk of troll-mob ppl to vent a bit....a virtual safe space from cold reality etc.
Understanding the true purpose of this place for most of this mob...is one step to getting towards empathy....then you learn to just ignore that and focus on those actually worth engaging here...and likely have some actual self-worth in real life too.
Hope this Wikipedia link comfort you a bit but here are simply facts:
According to the U.S. Census, median income was $63,179 for Americans in 2018.
According to your wiki link,
Pakistani American : $72,389 (adjusted 2016) which means, probably $75,000 (adjusted 2018).
#1 Now why would some living an above average life, compared to the rest of the country be butt-hurt about anything??
#2. While Democrats were giving whole sale H1-B (87,000 a years) to Indians they were also cutting Chinese and other neighbors quota, most Indian end up in IT or Nursing. This spike in average income is due to their sudden influx, port of entry and residence in major city (High cost of living, therefore similar living wage) mainly due to job and visa conditions.
Now $100,000 will only get you a 2 bed room apartment (on rent) in North California, where most of the IT jobs are. Similarly, H1-B Nurses working in expensive medical district (in downtown New
York or Houston) won’t be able to afford a decent house on their supposedly high pay due to cost of living.
Where as Most Pakistani immigrants arrived on a family immigration visa. Not hired, skill based or for job. They are living like a normal American family. Pakistani with $75’000 is living inside a two story house often start from a scratch, they are free to move around, quit job to obtain an advance degree. While H1-B Indian is restricted to location and job condition. Goras aren’t stupid, if they can hire local graduate (with 10 years of experience) to live off of $100’000 in North Cal, they wouldn’t be looking towards Cheap H1-B.
Another factor, many Pakistan women chose not to work (quality of life) after marriage, specially if they are not in professional field like doctors or running their own business. So $75,000 is most often is 1 person pay. Where $100’000 for Indian usually means husband and wife ( whatever ratio often 70/30 or 80/20, since only one is professional) .
Now same old grocery store excuse. Buddy, Business is business. Pakistan grocery store sell,
Indian, Pakistani, Mediterranean, Halal food items and advertise as such, and rightly so. Many Indian restaurant claim to be Halal for business when they are not.
