The best way to improve perspective taking is to see users up close.

There are highly innovative companies in the U.S., Germany, and India. And there are many stories of companies that failed to innovate in all those countries. This is good news because it means, regardless of your cultural background or where your company is based, it can become innovative.

The distraction, particularly of technology, impedes the innovative process. And when you add to that the distraction of working with colleagues who are in different time zones and/or who have a different approach to urgency and distraction, the potential for losing focus is abundant.

Smaller companies are often more homogenous. Don't simply increase your diversity because of the social pressure to do so. Instead, realize that hiring a more diverse team will give you a whole new repertoires of innovative ideas. And then develop a strategy for effectively using the diversity of your team.

Most people probably become more jaded the longer they work in the world of work.

I do think stories are one of the best tools for communicating across any number of cultures. But I also think there are wildly successful leaders who are introverted, disciplined, lead via spreadsheets and goals, and might not "appear" to be a great leader...but in retrospect, made a massive impact.

Generating diverse ideas requires being clear about the kind of input needed and creating multiple ways for diverse team members to share their ideas (e.g. use more than just a brainstorming session).
