I do agree that the US is rigid in its thinking. We accumulated a lot of wealth in the mid-20th century and a lot of national policy debates are around how that wealth is distributed rather than about undertaking new national ventures to bring in significant new wealth. It's understandable to a degree - we have a lot to risk by taking big national projects - but it feeds into our distribution problems because we want to be capitalist but we don't have enough new frontiers for capitalism to create opportunities for the younger generations.

I'd argue we're in a preservative/cost-cutting mindset rather than a generative/competitive mindset, which can be seen reflected in anti-trust policies. The philosophy has been to focus anti-trust around consumer benefit (eg lower prices) rather than to ensure competitive markets. We're more concerned with consumers' purchasing power than producers' opportunities.
