On the eve of Labour's conference John McDonnell has outlined plans to take back the railways, some or parts of other utilities, PFI initiatives and remodel the economy. He has even fleshed out how some things might be paid for through the issue of government bonds to compensate shareholders.
He thinks the railways could be taken back within five years, with the rest on a rolling programme over time.
It could all be a pipe dream likely to disappear under the full light of reality, but who knows? Having ideas is the easy part, delivering them is another matter.
However, one thing is certain, the ideas will be popular with a large section of the public - a vote winner.
