Since 99% of people have to study hard to pass LC (medium/hard), it effectively acts as a selector for employee conformity. People who play by the rules imposed upon them, who work long hours if corp wants them to etc. All the talk about diversity, but no diversity of thought. Only LC chasers. I genuinely believe this decreases innovation massively.
Nice belief, but good luck proving it.
I imagine the people grinding LC are harder working/more innovative than people who watched TV instead.
