Generalizations that are oversimplified to the point of lacking all nuance are probably untrue because there are bound to be exceptions. Instead, try including ‘many’, ‘most’, or such as an easy remedy.

Specifically, landlords can create value when they handle property management and maintenance (and the related costs) efficiently. It is wrong that greed has made that so rare.

There is no real need to use captured products though, so OP’s question is flawed.

Any desire to use said products (or not) needs to weigh the pros and cons of the captured products vs alternatives.
