Does Computer Science make more sense than Economics or Finance?

I am enrolling at a non-target school in Central Europe, one of the top universities here but unknown in the west. Hence, would it make more sense to study computer science which will likely negatively impact my GPA but given I am a non-target foreigner, I'd anyway have a difficult time of doing the IB and this way if I don't get into IB or decide otherwise, can rely on Computer Science for a tech job and hence still have a good salary. My plan hence is to after the bachelors study Computer Science as a masters in the US. However, on another hand I could try to study a masters in Finance or something and focus on finance internships to get access to banking that way but it seems recruitment that way is difficult so perhaps instead work in tech and after a few years do an MBA and pivot to associate status? Any advice would be appreciated.
