Well there are problems with the elites wanting to use us as slave labor and bleed us dry while they live a life of luxury, but that's not inherent to capitalism, capitalism is just the system they're exploiting to make that happen. They'll exploit any system for that, and capitalism at least ostensibly provides you with an opportunity to better your situation (when they're not doing everything they can to prevent that).

But having to 'grow up' and focus on responsibilities is just an inevitable part of life, and wage slavery aside, if anything the current regime encourages us to play around aimlessly rather than better ourselves, because playing distracts us and eternal children are eternal consumers.
