“Such reforms do not have any significant effect on economic growth and unemployment” is in direct contradiction of a central tenet in center-right politics in the West for the past 40 years. It bears repeating.
To reinforce that the concept that tax cuts for the wealthy creates growth and jobs is patently false. Some are still uninformed, or in disbelief, despite the data and scientific consensus.

I think calling this a "scientific consensus" is a bit inaccurate. There's very little consensus in economics (and one can argue about the level of science as well).
