Where do you find the bullshit that you talk AThing? The extent of it is actually quite impressive!
Let me spell it out for you. Tenants are not poor just because they are tenants. Tenants are not routinely exploited. Tenants are definitely not less powerful than their landlords. You may be aware of tenants that are all these things, but that has not come about simply because they are tenants.
Landlords don't want to give their tenants rights because they themselves would end up with even less protection from bad tenants than they already have. It is not because it would reduce their profit, or because it's expensive, or because it's inconvenient.
It is not inconvenient to have a tenant have the right to rent long term, nor does that reduce your profit, nor is it more expensive. If anything, it's the opposite.
It does not reduce profit if your tenant has the right to change the carpets when they want, or to let them decorate/make home improvements when they want. Nor does it reduce profit, nor is it more expensive.
So I realise I may be missing something here. If its not the right to long term tenancies that you want, and it's not the right to be able to make home improvements, what is it that you want tenants to have more rights to?
