Fair point, but the Union control could be reduced. If anything Union control has increased.
Actually the Union power has been reduced, but with no effect. Trade union membership fees use to contain a compulsory political contribution, which of course went to the Labour Party. Until the Tories rightly pointed out that this was unfair, so by law it had to be changed into a voluntary contribution. But that made no difference, most union members don't go into the nitty gritty of their membership fee so happily carry on paying just the same and Labour gets almost the same amount.
Now let me show you why your dreams of a reformed Labour are doomed by explaining why Labour did so well in the 2017 GE. It was because they had enjoyed a huge expansion in the party membership and therefore all those extra membership fees and electioneering volunteers.
But they were to a person all your hated left wing Momentum, mainly young enthusiastic people, hordes of them who got the Labour vote out.
Losing the unions means losing Momentum and all of the party income due to both, death by a thousand cuts. So they'd end up with the same fate as the last ex Labour attempt by the SDP.
The Labour party is trapped where they are due to factors entirely beyond their control. That's why they never change.
