You need to define what you mean by UBI before making such claim.
It might save money if it means a single benefit paid to everyone who does not work. This has existed in some form in some countries for a long time (e.g. France [1]). Results are debatable because there are several parameters to take into account and several parameters to play with when implementing such scheme. Certainly, "improved employment" is very tricky to achieve, if it is possible at all.
If UBI means handing money to everyone, then it is not a realistic prospect not least because it is un-affordable (the ooposite of saving money...)
