Populist Left Vs. Socialist Left

Here’s a thread on the differences between the populist left and socialist left. Off the top of my head, here’s a summary of each. The populist left opposes high concentrations of wealth, while the social populists want to create a utopian society where…I guess production of goods, services and wealth are shared by everyone. (Sorry if these are bad definitions.) How do you guys feel about these categories? Where do your politics line up, including if they fall outside of these two categories?
