But capital in itself isn't productive. What you saying is you can just produce/distribute/market a product for less than you could previously. I.e. your money goes further.

In order for this to be the case there must be reasons why this capital is so much more productive - one could then easily argue efficiency and/or cheaper labour.

I agree with you on many levels, especially on education. But I can't really compare Capital and labour in the same way you have - it's not either or.
