Yes, he promised he would build new airports in the USA and repair highways and bridges. Great idea, but the money the US government gives to the corporate sector as tax breaks and subsidies could be used for this purpose. I don't think any Western government will end corporate welfare polices, not on the left or right.

If Trump took the tax breaks away from the big end of town and spent it on things that benefit all American people like new infrastructure he would be a national hero. It won't happen though. If Clinton was president it wouldn't happen either. The pollies in Canberra and London also don't care about this issue.
