The difference is how the selection is done. If the fittest survive to breed, whatever fittest might mean at any given time and place, then it's evolution. If the ”less desirable” are culled or sterilized, while the “more desirable”; are allowed and encouraged to breed, it's selective breeding.
If the less fit and undesirable are allowed, encouraged, and subsidized to breed, it's liberalism.
“If the less fit and undesirable are allowed, encouraged, and subsidized to breed, it’s liberalism. “
liberalism punishes the successful more than it rewards the unsuccessful.
