Why doesn’t vegetable oil stay dissolved in vinegar to make a salad dressing?

In order for things to dissolve they must dissolve in a solvent similar to them (polar and polar or nonpolar and nonpolar) Oil is nonpolar and vinegar is polar therefore oil wont dissolve in vinegar

Vegetable oil is nonpolar, whereas vinegar is polar (about 95% water). Like dissolves like so polar and nonpolar dont mix.
