I almost never wore suits until I came over here. The first English school I worked for
required us to wear suits everyday, even when teaching kids; some schools even frowned on us taking our jackets off

This was teaching like, 5 year old kids. In a SUIT.

After teaching say, 3 kids classes, the rest of your shift was then teaching adult classes. I wasn't about to buy Armani or Ralph Lauren when I had to then roll around on floor mats with a bunch of 5 year olds.
My second job was for a dispatch company. I used to teach at Toyota, Mitsubishi, Pfizer, etc. I was teaching at their factories and I got to ride the train and taxis and all that, so wearing a suit became almost fun. Getting ties and tie clips, vests and all that was fun for a while. You get to appreciate casual clothes a lot more though when you wear a suit 5 days a week.
My job now lets expects me to wear a "shirt with a collar" but since no one checks I just wear Apple t-shirts

I've got one for every day of the week.
This
used to be the land paved with gold, but not anymore. One of my co-workers taught here in 1983 or 84 and was making up to ¥23000 an hour, that's like $200+!!
That was right near the height of the bubble though, which has since burst. Even 5 years ago it was still easy to get a pretty good paying job, but not anymore. You can't just waltz off the plane and have people just waiting to give you work. You have to go out and look hard, and there are a lot of crappy paying places, and places that are just crappy. "We'll just hold on to your passport for safekeeping." then when you try to quit, they won't give you back your passport

There are still places like that.
When
Eastend says he's working that hard, I believe him.
