That is an attack on free market capitalism!
Socialists (like you, obviously) scream in their best class warfare dialect - "Tax the rich!" despite the fact the "rich" pay far more of the "fair share" in the progressive tax rate structure.
I didn’t see anything about “taxing the rich” in that, but okay.
I interpreted it more as a statement about reforming the party’s image so it’s not falsely perceived as the banker party.
