Socialism is always collectivism, by opposition to liberalism.
Democracy and socialism cannot coexist.
Communism, Fascism and National Socialism are both collectivism, they just differ in the focus of their planning.
Liberalism's regulated competition is the best way to allocate resources in a complex society, which socialism's central planning cannot manage efficiently.
Central planning is the consecration of monopolies by the state.
Central planning offers idealists the appeal to force society to direct its effort towards grand goals that could/would not be achieved in an free individualistic, but it is only at the expense of the agents' freedom of choice of how to allocate their resources.
People are more likely to agree on means than on ends.
It is normal more often than none for legislative assemblies not to take any decision on a specific matter. Doing otherwise would be imposing a minority's view onto all the others because everyone's end are different.
The Rule of Law states that states should only promulgate laws based on general and predictable principles, treating everyone the same way a priori. Doing otherwise (deciding on the go and on a case by case basis) would be planning and would prevent agents from themselves planning their own ends.
Veil of Ignorance.
Increased security (to the detriment of freedom) given to a social group increases the risk for the rest of society, which might in turn make it profitable for them to trade their freedom for security. Security progressively becomes such a prominent part of social life and status that freedom seems a very low price to pay not to be cast away.
Socialist leaders have to repudiate moral principles and resort to practical ways they disapprove of in the progressive institution of a truly socialist regime.
Collectivism replaces absolute ethics by 'useful habits' to fill any gaps that direct orders may leave, to achieve the greater good.
The best way to make people adopt a new doctrine is to progressively change the words' meaning.
'That healthy contempt and dislike of power which only an old tradition of personal liberty creates.'
What are the consequences of political correctness propaganda?
Virtue only exists with choice: collectivism might be a way to indulge in collective selfishness that would not be permissible for individuals.
