making space between next values on y axis

  ggplot(dane, aes(x=państwo, y=całkowiteZarobki)) + 
  geom_point(aes(col=rodzajSportu, size=całkowiteZarobki)) +
  geom_smooth(method="loess", se=F) + 
  labs(subtitle="Area Vs Population", 
       y="Population", 
       x="Area", 
       title="Scatterplot", 
       caption = "Source: midwest")+
  theme(text = element_text(size=15),axis.text.x = element_text(angle=90, hjust=1))

PS. Any idea why it says 100 milion dollars is the lowest value? It clearly should be on top of y axis yet it stays at the bottom.
