I think that might be an ambitious guess regarding Riseup's intentions - they don't make any such distinction. They demonstrate a typical uninformed, knee-jerk, radical anarchist philosophy.
For reference, a definition of capitalism:
"An economic system in which investment in and ownership of the means of production, distribution, and exchange of wealth is made and maintained chiefly by private individuals or corporations, especially as contrasted to cooperatively or state-owned means of wealth."
I don't agree that the US standard of living is decreasing "because those who have capital are leveraging their capital against those without." In fact, the US has an extraordinary high standard of living, far better than 20 years ago (just look at a grocery store, your average automobile or home, or what people do on vacation.) If it is plateauing or declining the last few years, it is for other reasons, including:
- An unrealistic increase over the last 10 years built on credit. It will take a few years before our economy catches up with that.
- A wasteful and destructive government education system rotting for lack a free enterprise and undermining our economy as a whole.
- Wasteful government spending and borrowing - trillions of dollars spent on corruption and war.
Nobody is using capital "against" anyone - I'm not even sure precisely whbat it means, yet I'm quite sure it's false.
