US Authoritarianism

Can you provide some reading for context? I'm looking into Mussolini and at least according to Wikipedia, where you seem to have directly lifted most of your points, the story is quite a bit more nuanced than you're presenting.

Some quick things I found:

Although a disciple of the French Marxist Georges Sorel and the main leader of the Italian Socialist Party in his early years, Mussolini abandoned the theory of class struggle for class collaboration.

Economic policy in the first few years was largely classical liberal, with the Ministry of Finance controlled by the old liberal Alberto De Stefani. The multiparty coalition government undertook a low-key laissez-faire program—the tax system was restructured (February 1925 law, 23 June 1927 decree-law and so on), there were attempts to attract foreign investment and establish trade agreements and efforts were made to balance the budget and cut subsidies.[26] The 10% tax on capital invested in banking and industrial sectors was repealed while the tax on directors and administrators of anonymous companies (SA) was cut down by half. All foreign capital was exonerated of taxes while the luxury tax was also repealed.[27] Mussolini also opposed municipalization of enterprises.[27]

In 1924, the Unione Radiofonica Italiana (URI) was formed by private entrepreneurs and part of the Marconi group and granted the same year a monopoly of radio broadcasts.

The Pact of the Vidoni Palace in 1925 brought the fascist trade unions and major industries together, creating an agreement for the industrialists to only recognise certain unions and so marginalise the non-fascist and socialist trade unions. The Syndical Laws of 1926 (sometimes called the Rocco Laws after Alfredo Rocco) took this agreement a step further as in each industrial sector there could be only one trade union and employers organisation.

In 1930, the National Council of Corporations was established and it was for representatives of all levels of the twenty-two key elements of the economy to meet and resolve problems...One consequence of the Council was the fact that trade unions held little to no representation whereas organized business, specifically organized industry (CGII), was able to gain a foothold over its competitors.

A key effect that the Council had on the economy was the rapid increase in cartels, especially the law passed in 1932, allowing the government to mandate cartelization...Cartels generally undermined the corporative agencies that were meant to ensure they operated according to Fascist principles and in the national interest, but the heads were able to show that cartel representatives had total control over the individual firms in the distribution of resources, prices, salaries and construction.

A lot of these things seem to be directly in conflict with the elevation of the working class, but rather strictly state-corporatist and explicitly hierarchical in their implementation. Simply nationalizing industries doesn't really equate to socialism I don't think.
