Most “socialist” parties in Europe are neoliberal parties that no longer advocate true socialist economics. Macron is a “liberal,” meaning his economic polices resemble what the Wall St. Journal editorial page would want more than socialism. Think Tony Blair. Like the WSJ editorial page, Macron is a hardcore open borders advocate. He’s probably the worst candidate on immigration the election. Genuine socialists in Europe will tend to at least admit that massive immigration can hurt workers, neoliberals maintain that immigration is 100% beneficial and has no drawbacks.
WSJ editorial page might be bad on some things like immigration but no, they are not nearly as far left as this so called “centrist”.
