The evils of which you speak (and we agree, they are evils) were brought in to being by a land holding cartel in order to create scarcity and increase its wealth. Socialism was a failed attempt to deal with this scarcity by controlling labor, capital, and land. Georgism , OTH, frees labor and capital, and allocates to society the wealth that it created, the value of its land.
Interesting, but I cannot find a single historical success story for Georgism in practice.
