That's likely true for many people, but there percentage of people that are so dissatisfied that they want to emigrate is very large - 57% of 18-30 year olds indicated they would emigrate if given the chance in a CUHK survey earlier this year:
"Around two-fifths (38.9%) of respondents indicated they would emigrate to other places if they got the chance...younger people (e.g. aged 18-30: 57.0%) had a higher tendency to emigrate.."
"Top pushing factors for emigration among those inclined to move were “dissatisfaction with SAR government / government performance / Chief Executive / high-ranking government officials” (11.0%), “overcrowded living conditions” (10.5%), “too much political dispute / social cleavage” (10.3%), and “slow economic growth or bad economic prospect” (10.3%)."
