If you went back to Marx's time and you were a worker, you might well look at the mess and think the only way to fix it is to sweep it all away. Early capitalism was brutally exploitative, and workers had little legal protection for anything short of outright murder. Living conditions were harsh and working conditions were worse, and there was nothing you could do about it because you had no political clout, even if you had the franchise, which you probably didn't.
But there's been almost two centuries of struggle and experimentation since then. If you look at the countries with the highest human development index [note], you're looking across the board at countries with a market economies, but also with robust legal protections for worker safety and rights, environmental and consumer protection, and typically fairly generous social welfare programs. Average people in places like Switzerland, Norway, Australia and the Netherlands enjoy a degree prosperity, liberty and security that disprove the axiom that market economics has to be swept away for common people to be able to live a decent life.
Nobody living in such a place would come up with Marxism, although people may come to it for historical, cultural or romantic reasons. If human wants weren't infinitely expandable, they'd be living in what would look to a 19th century worker as a post-scarcity society. And as long as they don't infringe on other peoples' rights, the masses can live in a degree of personal freedom unheard of in prior ages of history. Sure, you'd be more personally free under absolute anarchy, but the marginal benefits and costs aren't that attractive.
note: Hong Kong is a historical odd man out on the HDI list, for obvious reasons.
