there is a lot of nostalgia about kampung 'village' living in Singapore (mostly by people who have never lived in them!) its kinda like how we idealize blitz spirit. in the uk apparently in the old days, everyone could grow their own vegetables, everyone knew their neighbors, there was such community spirit etc etc etc
Most people in singapore did not live in private houses in 1965. they lived in wooden huts with no plumbing, no toilet and there was no protection against flood and fires. Its why they moved the population to the high rise flats cos at least even if you did not have your own garden, you at least had your own toilet and you were not likely to lose your roof overnight.
The issue isn't really about whether people should live in a flat or a house. Its about whether the state should provide decent housing for the majority of the population who cannot afford to buy housing on the private market without severely compromising their own standard of living. My grandparents in singapore bought their own terraced house with garden when there was no public housing scheme in Singapore (my grandfather used to have an aviary in his garden) but of course it was very hard. My grandparents were not wealthy; my grandfather was a teacher and my grandmother was a secretary. They basically couldn't live with their own children for 7 years because they had to work so hard to save the deposit and therefore sent their children to live with relatives while they worked long hours during the week. My grandmother always talks about how she cried when she had to leave her children on Sunday (but that was the price to pay for home ownership back in the days when home ownership was not subsidized). Thankfully no young singaporean today has to go through such torture just to have a roof over their head. Young singaporeans have the choice- they can buy private property if they can afford to or they can just buy a government flat. Or they can buy the government flat and upgrade to the private condo/house in later life.
This decision on the part of my grandparents is also the reason why no one in my dad's side of the family has ever bought government housing in the last 3 generation (this is mainly because my dad bought a house with my grandparents & because my uncle and myself moved overseas). But my father is always encouraging people to buy government housing because he believes that it is a good deal and young people should not spend so much time/energy/money on their primary residence
I believe there isn't enough public support for mass housing schemes because people are not in such desperate circumstances like my grandparents' generation in Singapore. However, one day, they might be and there might be more support then. If private rent rises to 90% of the average income combined with £4000 energy bills etc, then that might be a tipping point. Even home owners may not be safe if mortgage rates increase and houses are more expensive to heat than flats. Even for middle income families who own property, you would be more able to pay heating and electricity bills if you didn't need to spend so much money on a house. yes everyone wants to have a garden and a big house but if its a question of survival, then the variables are very different...
