It does not deal with Capitalism.
Capitalists produce goods and service.
Here we are dealing with banking groups who issue money through the ECB, applying legalized usury towards the same States.
So States are the victim here.
Banks are an important method by which capital is acquired to create industrial production facilities; without such capital-gathering institutions, industrialization would be close to impossible in a modern capitalist economy. What you call "legalized usury" is in fact the primary means by which banks can remain in business, and the primary motivator for industries to remain competitive and thus profitable.
You are falling prey to the classic corporatist ploy of separating "good" capital from "bad" capital - as if the direct exploitation of labor at the hands of industry-owning capitalists was somehow more virtuous and moral than owning the capital that faciliates this exploitation of labor in the first place. This ploy is one that was first pushed by industrial capitalists, and is almost always a self-serving one - a method to mask their own exploitation in favor of an easily-demonized "outsider" enemy. But fact is that they are all cogs in the same machine.
Talking about Italian producers specifically, I cannot help but point out the blatant exploitation of foreign workers at the hands of these supposedly virtuous, moral, "productive" industrial and agricultural facilities, where people are working under conditions that should turn every decent human being's stomach.
Blaming "international banking" for this would be both facile and a tad disingenuous, in my opinion, since nothing but their own drive for ever greater profits is driving Italian capitalists to exploit labor to such a staggering degree.
The state - and here, in particular, the xenophobic-nationalist movements that drive the exploitation of these foreigners the hardest, via their policies of inequal rights and unfair treatment for foreigners - is very much complicit in this, and we can see this every time people start protesting these conditions, only to be brutally put down by organized state violence in the form of tear gas, water cannons, and police batons.
