Why did Solon provoke discontent among both the demos and the nobility with his reforms?

Despite the fact that Solon introduced many laws and reforms, both aristocrats and demos were dissatisfied with his works.

The nobles did not like the fact that Solon sought to equalize them in rights with the poor. Solon also deprived hereditary privileges. That is, now a person could hold a position only according to the results of his activities and deserts, and not because he was born into a noble family.

Demos was unhappy with the fact that Solon had not carried out the redistribution of the land. That is, the impoverished peasants lost land, and they passed to more successful people. Many poor people did not have land.
