Just because another system would fail these people too doesn't mean that our current system in how it works isn't failing these people. And just because big bad communism is another shit extreme, that doesn't mean that there are no other economic systems, or if you prefer, potentially variants of our current economic system, that would be better.
I won't pretend to know the solution, but either capitalism in general or the capitalism we currently have, with for example its misaligned incentives, exploitation and death traps people live in, sure seems to be a huge part of the problem.
