This is a limitation of the current borrow checker. I think there are some efforts going on to improve on this situation, but right now that’s what we have to work with.

The borrow checker can keep unnamed values around for a single expression, but not beyond that.

Depends on how far you want to go left. On the more extreme side, these people want to abolish capitalism entirely and replace it with a communal system (workers owning the means of production). Democratic socialism is a very moderate form where capitalism is kept, but people get a fair chance of living in the system (usually through monetary assistance), no matter what family they come from and what their abilities are.

Liberals are pro free market and capitalism. Leftists are pro social programs and taxing the rich.
