CASE STUDY
china's one child policy
put in place because pop was too big, i billion in 1970
was relaxed after sichuan earthquake
rules
can't marry until 20
only one baby
boys were more wanted
lots of girls died in orphanages
benefits to people
5-10% salary rise
priority housing
free education & healthcare
if disobeyed
10% salary cut
fine was so big would bankrupt you
no free stuff
if 2 only childs had baby they can have two
rich ppl would have two as can afford fines
4,2,1 problem
wasting money on pensions as lots of old
not enough independent ppl
