How long do you think it will take the US to build a 59 billion dollar blood fraction-industry and how many people from the Hood or some town in Appalachia will be employed in those industries as medical technicians or engineers building x-ray machines?
Can there be a net benefit in the long-term for the very poor, maybe, yes: You need more truck drivers, janitors, plumbers, cafeteria staff, security, etc as well for every new high tech-factory/lab opening in the united states, but in the next few years, that's a massive additional cost with almost no benefit to the poor.
