Reformism is a bourgeois deception of the working class where the capitalist class retains control over the means of production. It is only possible when workers do not have a Dictatorship of the proletariat.
As described by Lenin:[1]
"Unlike the anarchists, the Marxists recognise struggle for reforms, i.e., for measures that improve the conditions of the working people without destroying the power of the ruling class. At the same time, however, the Marxists wage a most resolute struggle against the reformists, who, directly or indirectly, restrict the aims and activities of the working class to the winning of reforms. Reformism is bourgeois deception of the workers, who, despite individual improvements, will always remain wage-slaves, as long as there is the domination of capital. The liberal bourgeoisie grant reforms with one hand, and with the other always take them back, reduce them to nought, use them to enslave the workers, to divide them into separate groups and perpetuate wage-slavery. For that reason reformism, even when quite sincere, in practice becomes a weapon by means of which the bourgeoisie corrupt and weaken the workers. The experience of all countries shows that the workers who put their trust in the reformists are always fooled. "
