I don't think the Brits done anything for anyone out of the goodness of their hearts however I'll give them
- the industrial revolution : steam engines, railways, clocks, compass etc
- the scientific process
- democracy ?
- we inherited their legal system, constitution etc
- production of steel ( bessemer process )
- chemistry ?
- better bridges / arches / steel bridges
- World War 2
Most was sold through capitalism not donated, so can't exactly claim the moral high ground on it.
