What we need is a “fourth way” of politics, a system that makes billionaires impossible, that fosters public services, including housing, cares for the needy, etc, but also promotes entrepreneurship, taxes progressively, guards society against the excesses of capitalism, etc.

Oh, you mean, social liberalism?

Social liberalism: Social liberal parties stress civil and human rights and favour a social market economy.

Or the New Deal democrats of the Great Society reforms?

The Great Society sought to build on the legacy of former President Franklin D. Roosevelt’s New Deal reforms of the 1930s, and planned to use the power of the federal government in order to address economic inequality, improve education and healthcare, and promote civil rights.

There’s that word people on here hate again: liberal. You guys are reinventing positions from willfully forgotten history of liberals & the Democratic party.
