Less money spent on enforcement of victimless crimes like smoking pot or being a homeless person, more money spent on actual rehabilitation and treatment, less money to the corrupt people profiting off of private prisons. Fiscally responsible, and gives law enforcement more time to go after people who ACTUALLY harm people or steal from them. i.e. do their jobs protecting the public, not be glorified tax collectors or morality police.
More money for education, more money for transportation and infrastructure, more regulation of predatory business practices (privacy/net-neutrality regulation on tech companies).
Illegal immigrants? Mostly work harder than you ever will, and they aren’t even eligible for benefits. At 4.2% unemployment, it’s not like Americans are hurting for jobs in California.
