You've brought up what you see as a problem. Before addressing that, we should think critically for a moment. Just because there is a problem, does that necessarily mean that privatization is the only solution to that problem?
Your problem: Regional FOs get paid more per flight hour than low level facilities in the FAA.
That's awesome for them. They also only get paid for every hour the airplane is flying. Do you want to only get paid your hourly wage only when you work traffic? They don't get a pension. They are usually 50k in debt because they have to pay for their own training. Also, they were hugely UNDERPAID for literal decades before this. The companies that are now paying them what they deserve (for the time being) only did so after there was no other option.
