Did Marx believe in the increasing immiseration of the working-class under capitalism?

In Ernst Mandel's introduction to Das Kapital he says Marx abandoned the idea of 'increasing immiseration' of the working-class which he had advocated in the Communist Manifesto. However on Wikipedia it says, quoting from Das Kapital vol. 1:



Within the capitalist system all methods for raising the social productivity of labour are put into effect at the cost of the individual worker [...] All means for the development of production undergo a dialectical inversion so that they become a means of domination and exploitation of the producers; they distort the worker into a fragment of a man, they degrade him to the level of an appendage of a machine, they destroy the actual content of his labour by turning it into a torment, they alienate from him the intellectual potentialities of the labour process [...], they transform his life into working-time, and his wife and child beneath the wheels of the juggernaut of capital. But all methods of the production of surplus-value are at the same time methods of accumulation, and every extension of accumulation becomes, conversely, a means for the development of these methods. It follows therefore that in proportion as capital accumulates, the situation of the worker, be his payment high or low, must grow worse. Quote:

i.e. that he did support the 'immiseration thesis'? Any resolutions to this? It seems to me this is actually a bad interpretation of Marx from wikipedia. Since Marx clearly says in the quote he is not referring to wages, and by 'situation gets worse' he means the degree of alienation as capital accumulates. Whereas Mandel clearly refers to wages, and it is by this measure he argues Marx stated it's quite possible for workers to be 'better of' materially, that is with higher wages, but they are nevertheless in the process more alienated etc. from their species being.

Any thoughts or resolutions?
