In my experience this is not at all the norm. Maybe there's the occasional CEO or something that feels secure enough to dress casually, and if they're attempting to be public figures in some way they'll dress casually so as to promote a more approachable and down to earth image... Otherwise, while we're not quite as "suited" as we were 30 years ago or as the Japanese still currently are, from what I've seen most people dress "business"-like when doing anything work related.

To convey disbelief that something is done would be a clear indiction that you feel it annoys you as you say in the OP "(I can't believe that Los Angeles or New York would find this acceptable),"

and it's funny based on your nationality as it would be if I was to make a thread on hear asking why Australians wipe their ass a certain way, the impact of the question and the answer makes to my life is nil as should be how someone goes to work casually dressed in US.

But yeah if you weren't annoyed by it and you think that feigning disbelief or shock about something like this is normal then power to ya, I'm out though this thread is a low point on VGchartz in all the time I've been here.

Because wearing a suit and tie doesn't make you smarter, despite what people dressing up for work like to tell themselves. Suiting up for work is really just an attempt to manipulate people into thinking they're smart or wealthy, albeit often a successful one.

Tech culture developed a strong anti-suit mentality. Look at Jobs, Gates, Zuckerberg, etc. There's a saying, "never trust anyone wearing a tie", it originates from businessmen knowing essentially nothing but pretending they know more than everyone else because "selling", trickery, and manipulating people was how they earned a living. Their whole existence is to profit off the work or ignorance of others. Faking it until you make it may work on Wall Street or in Advertising but doesn't work when the product isn't just a personality, brand name, or snake oil but requires actual superior functionality/features. Wearing a suit doesn't increase your IQ.

Even now, he must be proud of me then. That's my daily outfit... 

Thought gym clothes are formal wear of the slavs and russians.

Depends on the company. I have 2 jobs and they're both practically in the same industry. One requires me to wear a proper uniform and the other tells me to wear whatever the hell I want. So I typically go in skinny jeans, t-shirt, cardigan, and regular shoes. However I have coworkers who go more casual than me and go in practically their pajamas

At the place I worked, a data management company, it's business casual (AKA pretty much jeans and polos) but I've never seen anybody in gym clothes under any circumstances. Not sure where you got that impression from.
