No, just the one.
So can you choose not to pay your mortgage/rent and choose not to pay for childcare? Can you choose not to pay tax?
A couple with 2 kids earning €130k a year with a €450k mortgage will have an income after tax (€40k), mortgage (€34k-€38k) and childcare costs(€20k-€24k) of around €30k a year.
A couple with no mortgage and no kids on €40k a year will have an income after tax, mortgage (and childcare costs of around €38k a year. They'll have around €35k less outgoings because they are rich; they own their own home and so don't have to pay for the use of someone else's wealth via a mortgage or rent.
So move to a home that is too small for your family or move further away and move your kids to a different school, have a longer commute and possibly higher childcare costs, be further away from parents, family and friends? Most people will sacrifice to stay near their social infrastructure. In many parts of the country there are no cheap homes.
In most cases they are retired or older people who bought a home before 1990. They now have no mortgage, no childcare costs, pay almost no income tax and benefit from a net social transfer. Fair play to them and all that, I think that's great, but they are rich in that they have substantial net wealth.
