Politics as a compass — four poles, three rooms.
Four poles span the main axes: top is the upper class (top income quintile), bottom the lower class, left and right the ideological poles — the latter backed by original party programmes. Click a pole for the structural situation. At the centre: three solution spaces where overlaps might emerge.
Housing crisis
Housing cost burdens hit each stratum differently. Four positions, three solution spaces, one constitutional frame.

Politics moves between poles. Here are three of them — slide the handle and see the documented consequences of each position. No recommendation, just a map of the possibility space.
Tenant protection ↔ Investment incentives
How much tenant protection — and what's the cost on the investment side?
Moderate regulation under OR. Existing rents 2006-2021 rose much more than cost-based justified — per BASS study, about CHF 78 bn redistributed to landlord side. Reference-rate cuts only passed on in 1 of 6 rentals.
Redistribution 2006-2021: CHF 78 bn. Updated: annual rent payments ca. CHF 42 bn.
Inward densification ↔ Zone expansion
Do we grow inward or outward?
Densification happens, but via replacement construction. In the five largest agglomerations, up to 63 % of new builds are replacements — structurally displacing low-income tenants since new occupants have notably higher incomes.
63 % replacement builds in top-5 agglomerations. Median income in replacements 14.6-38.7 % higher.
Non-profit ↔ Private market
Who builds affordable housing — cooperatives or the market?
Per the updated BWO 2024 statistic, co-op flats make up ~3.7 % of all Swiss homes, ~4 % per umbrella estimate (~165k-170k flats). Market impact at this share is small and barely visible in rent indices.
BWO/BFS 2024: 3.7 % co-ops (152k of 4.1 M). The often-cited 7.9 % comes from older / broader definitions (incl. public sector, foundations).

Expand non-profit housing
3-7JTop up the revolving fund (Federal Council proposes CHF 150 M for 2030-2034), interest-subsidised guarantees, cantonal/communal land leased to cooperatives. Cost-based rents permanently 20-30 % below market.

Methodology
Stratum definition follows BFS income quintiles (Q1 bottom, Q5 top). Ideological poles are exclusively backed by official party programmes and parliamentary motions — never attributed as stereotype. Solution spaces are not recommendations but documented options from scientific and political debate. Where a source is uncertain, it is marked (pre-advisory-review state).
