With all due respect...
I also don't agree with his conclusions because I don't believe wealth equality is any sort of natural human state, even in a free market. But if you're going to post that chart you should also post or reference
the rest of the ongoing FT vs picketty dialogue.
...note that a 44% wealth share for the top 10% (and a 12.5% wealth share for the top 1%, according to the FT) would mean that Britain is currently one the most egalitarian countries in history in terms of wealth distribution; in particular this would mean that Britain is a lot more equal that Sweden, and in fact a lot more equal than what Sweden as ever been (including in the 1980s). This does not look particularly plausible.
What is good about the conversation is it offers data so perhaps we can start moving on from everything defined as socialism is theft vs socialism for the rich, to realise that most people seem to get stuffed whatever the -ism. To start asking why, whatever our biases. As the OP inferred, maybe things are changing and how we transact and think of money will definitely change. Bitcoin and cryptos have a role in that future and would be good to see more focus on solutions before they're made for us - whether by the state or business.
