The benefit is too tangential to any corporation's interest to justify the cost of launching people into space. Things only balance out at the state level.
Even when - IF - the foolish US plan to privatize launches finally pans out, it will still be merely contractors working for big government payouts, not out there making money on anything resembling a market. It will be just like the bloated Pentagon budget, entitled companies making overpriced garbage to please corrupt politicians and bureaucrats at the treasury's expense.
