If you don't have a public facing job, then does it matter if you wear a t-shirt and jeans to work

I think it can. I've had a couple of jobs where I needed to wear a suit to work (or at minimum, dress shirt, tie, and slacks) even though my job was not customer-facing. It had its annoyances but in some ways I think I took everything a little bit more seriously when I was at the office. Probably for the same reasons that uniforms are found to decrease behavior problems in schools that require them. There's sort of a mental switch that is thrown when you put on your suit, you switch into "work mode" and then when you take it off at the end of the day you switch to "not at work mode" and it actually can help with work/life balancing.

What works for you doesn't necessarily work for everybody. For example I am completely unable to work from home, so even though most of my career I worked remotely, I prefer to rent an office, even when I have the freedom to stay home.

But not all people have such preferences. I know people that are quite happy and productive while working from home. And personally I come to work in slippers and tee-shirt during the summer, with no effect on my seriousness with which I treat work.

A big part of uniforms is so kids (mostly girls) don't play clothing status oneupmaniship bullying on each other.
