Abundance theory and economics

MY question is this: Does the idea of abundance apply to economics? And if so, to what effect?

That's my question.

I have heard this theory, that abundance is real... That wealth is created (Not taken from others). That win-win situations are always there.

There are websites that push this idea, but I wanted to post this here, because I felt like ATS has more points of view, and more open minds!

Now, say I create wealth...

Did I simply improve my area's economic strength?
Did I truly create more money for everyone involved?
Did I take money from someone else, by taking away the opportunity for them to profit on it?
