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.
I just want the ECB to be 100% public, that is owned by public entities whose aim is not the profit maximization.
Btw the Central Bank of a country is supposed to be owned by the State. By the treasury, because the State only has the juridical legitimization to issue money.
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.
I think that labor is a sacred right, an exploitation is really awful. And illegal.
Capitalists exploit people just because by exploitation they reach the profit maximization.
Profits are never enough to them.
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.
Quite the opposite. It is the Banking system which benefits from the Capitalists' profit maximization.
Farmers who are paid fairly and who live a dignifying life, are not on their list.
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.
Quite the opposite. The so called "nationalist movements" here are against illegal immigration and want Italians to work on the fields and on farms.
Not only because of exploitations of immigrants is awful, but also because they will not okay an ethnic replacement.
