It's a wonderful aspiration to own your own home and for your children to do so too, but let's not forget that it's not that long ago that very few people except those in higher employments or with inheritances could afford to do so.
I'm not saying whether it's right or wrong, but historically in the UK home ownership has not been the norm, and everybody just got on with it. Now everybody seems to see it as a right, which can be setting unrealistic aims really.
Not everybody wants to own, and something should be done to address high rents in areas where this is prohibitive (we moved to the north west where both house prices and rentals are far more reasonable in a lot of areas), but I'm not sure that penalising good landlords who look after their properties and tenants is the way to go.
Social housing is a wonderful idea, but if we converted all the BTL properties to social housing it would create a double burden on the state, both in terms of maintaining these homes (the capped rents rarely cover proper maintenance and running of social housing) and the burden of providing additional pensions to those who are no longer saving for retirement via BTL properties and investments (this is a large financial factor in pension planning, as many investment companies use property vehicles).
It's one of those impossible arguments, really. Yes, I do feel sorry for hardworking people who invest in properties as a means of retirement savings, but I don't really feel for those (probably fewer) money grabbing bad landlords who don't look after their properties or treat their tenants well.
