I don't think so. First and foremost, house insulation can also be done when you rent out the apartments (but often the landlord has little incentive to do it).

Second, electrical cars are expensive, yes, but they don't subsidize the well-off because they would have bought expensive gasoline cars otherwise. Who really profits from the subsidies is the middle class: You can lease small electric vehicles quite cheaply and if I am not completely mistaken, you can buy an electric Dacia for 10k€ after subsidies. So yes, this is not for the working poor. But the working poor hardly invest anyways, so it is really difficult to setup an incentive program for them.
