Because the major thermodynamic driving force is $\text{entropy}$ not $\text{enthalpy}$.

#### Explanation:

$\text{Entropy}$, the statistical probability of disorder, is the fundamental thermodynamic force for chemical and physical change. Certainly, a solution of a salt, has more entropy, more randomness, than an undissolved solute.
