To be honest PLA infantry do feels like upgraded North Korean army. This white cat, black cat don’t matter if they catch a mouse ideology is so old fashioned. A properly dressed military personell also gives an psychological impression of competence & professionalism. A random enemy soldier would react differently against random person wearing US infantry camo / PLA camo.
Humans since ancient age has always tried to appear meaner, stronger, bigger by using various makeups, ornamnets, outfits to psychologically demoralize its opponents.
I bet atleast half of the twitter keyboard warriors will stop spamming war against China if they see how modernized Chinese military personnel appear.
The fitout and procurement of any entity in the military is primarily dependent actual utility, not aesthetics.
And buying equipment with actual utility, costs actual money as well.
The PLAGF, until recently, placed individual infantry fitout quite low in terms of priority compared to everything else they needed to develop and procure (mechanization, artillery, expansion of army aviation, informationization, etc) -- and the PLAGF in turn was quite low in terms of priority compared to the PLAAF and PLAN.
That's just a function of having finite funding and a reflection of how much modernization the PLA had to do.
For now, I suggest you count your blessings, and be grateful that at least they are issuing one or two types of optics for their service rifles that look like they are going to eventually become standard. In the 90s and 2000s that would have been a luxury.
At the end of the day, it is dependent on finite money and opportunity cost.... and in terms of bang for buck, infantry fitout for most forms of warfare, is relatively low in efficiency.
