If the younger generation has soured on capitalism it's because they've come of age at a time when the entry level situation is fairly dire and in some cases hopeless. You can skip college and remain on the lower end of the working class – an exception being those who find a skill in demand and escape neo-vassalage by means of becoming self-employed.
Or, you can take on massive debt which more or less enslaves
you to a job (an employer) as you are compelled to keep making your payments.
And by the time you're done you've undoubtedly taken on many more. It's a trap
and some young people have realised it. For many of that generation, adult life
properly speaking, an age of autonomy and social establishment is nigh on
impossible before one is in their thirties. The system is immoral and exploitative
and those who are living in the bottom tiers realise it and thus they're willing
to entertain other options, all the more when they begin to understand the
American system and its priorities, as opposed to the model of the social
democracies in Europe – which have elements that many Right-wing Americans
erroneously associate with Marxism.
