More importantly politicians rely on being able to selectively dole out support and money and a UBI would take away that ability and thereby a lot of the direct influence over segments of society. If anything I am quite sure businesses would be more than happy with UBI because they would not get people who HAD TO TAKE THAT JOB and instead people who took it because they wanted it. A UBI would never be high enough to allow you to skip work unless it also provide absolute basic housing too and food.
