SO DO THEY WANT TO HIRE MORE PEOPLE TO ANSWER THE PHONE? OR IS IT TO PURSUE UNCOLLECTED REVENUE?

How about if the IRS uses the resources it has to shore up cybersecurity, instead of to hinder the activities of the administration’s political adversaries (I don’t think there’s much serious dispute about that fact anymore)?
No, the first things we hear about when a cut to the IRS’ budget is proposed is that they won’t be able to hire enough people to answer the phone, or that it will negatively affect their tax collecting efforts.  So, tell me, IRS proponents, which is it?  
Why is it that every time a government agency is faced with budget cuts, the first thing they do, or threaten to do, is cut the most visible services?  How about not paying bonuses to employees who don’t pay their taxes?  How about no more training junkets and in-house video productions?
