Subsidies are an incredible tool when used well, like when they funded a bunch of utility cooperatives that electrified rural US. Maybe you’re asking why we should because propping up the car industry when public transit and bike infrastructure should be subsidized instead, rather than challenging subsidies, though.
Allow me to gas Finland up a bit more. They’re higher than Germany in terms of innovation (triadic patents per capita), they have semi-democratically owned grocery stores with 90% of the country being a member/co-owner, they have 60% union density and a Ghent system (like Sweden, unlike Norway), their housing prices were among the few in Europe falling - after the government started their Housing First initiative and built social housing for the poor, their education system being so good (despite being relaxed unlike e.g. Singapore) and state-funded instead of private… life is pretty good in Finland.
