Why do you think Capitalism has meritocracy as a core component?
Capitalism is a system where capital needs to be converted into more capital via economic action (reinvestment) rather than just sat upon.
Capital will always find ways to grow, if there are laws - they will be lobbied against. Or those with main market share will work together to stabilise the market and squash competition.
