Why are they speaking english in Schindler's list?

Many english speakers don't like to read subtitles.

you could say that about a lot of movies.

Because I don't understand German

It really does bother me a lot also when it is a serious film. I love foreign films in native language with English subtitles.

It's not a foreign film. Having said that I do like it when a movie featuring both foreign characters and domestic characters have it that the foreign characters speak their native language, such as The Longest Day or Tora! Tora! Tora! On the other hand it doesn't bother me at all when the foreigners speak English, like The Great Escape or Midway. I don't think there are any native English speaking parts in Schindler's list, so it does make sense that the film is in English, as it is an American made film, such as Valkyrie with Tom Cruise.

Doesn't make sense that ancient Romans always speak English with a British accent either. Not that I wanted Latin or Greek dialogue with subtitles, but still.

This is such a petty complaint. Personally I don't know any language but English so I really don't want to watch an entire movie in subtitles and miss cool things happening on the screen that I can't see because I am too busy reading subtitles to notice them.

Have you ever seen an English language movie in a foreign country (in a theater) with that country's language in subtitles? I did once. It's a weird experience!
