It is if it is a classification of country.

It isn't a compliment

[Edit] To be clear, it's the modern term for what used to be "third world", since a lot of countries that would be considered "third world" (Africa and Asia minus Japan) are now industrial or post-industrial.

I read this as needing to have the old money behind the movement.

I'm not entirely sure how we would do this, as old money is hard to find and has entrenched power. Other countries can do this with new money, as taxes and investment tax offsets encourage people to invest and make everyone better off while they make more money. This can be either like the US where it is all new money, or France where the old money was redistributed by blood.

Taxing old money is hard, and increased interest rates mean they want to save it. To redistribute it, I can only assume we need to:

1. Stop hording, so essentially we need to get interest rates down low so investments are the only place for old money to go
2. Correct our tax brackets. Punish those that make over £200k (essentially top execs) to discourage the top management from sharing the profits, and stop treating £100k like it's a lot of money. I could easily make that in other European countries or the US without being an executive.
3. Increase minimum wage and pull everyones standards up with us.

I don't but when I do I'll post them here.
