Capitalism will always be in deep trouble. The fundamentalMy experience is the same honestly. Even though Capitalism has been in deep trouble for many years (since the financial crisis in 2008 for example), people are not receptive to Marxist ideas at all and are quite hostile to it. This includes the working class and most of the membership of far-left parties in Britain or America these days is from young people (primarily students) and maybe a much older group left over from the 1960's and 70's. People of working age don't typically engage with the philosophical, political and social question Marxism raises, partly because they don't have the time, but also because most of them don't care that much either.
problem is that people have too much economic liberty.

black market. One picks one's poison. Mine is capitalism.
