And they're doing it by parasitizing and sitting on limited resources while inflating their value.
Hm. Maybe. For example, I'm temporarily living in one right now which I hope is going to provide a modest pension for myself, because my private pension tanked, partly because I had to stop paying into it in 2007 because I took a 50% pay cut in the recession, and have since lost that job when the firm closed. I bought the house (on an interest-only mortgage, which together with other on-costs, including rates and insurances, the rent does more than cover, but not by much, and that's when it is let out which it currently isn't) about 2 years ago, from someone who had bought it for similar reasons 10 years before that at double the price I paid for it, so despite the trouble of maintaining and renting it out for 10 years, he lost a lot of money, as did others like him.
Currently, I am dealing with a couple of major issues to do with very unexpected but necessary repairs (for example there was an oil leak from the boiler last year which meant that the floor had to be dug up to treat the contamination) not to mention problems renting during Covid19, coupled with the introduction this year of a draconian local council initiative to try to remove renting licences in this area for dubious political reasons, so in the short to medium term I am not going to see a profit, and with the talked-about 'largest recession in living memory' potentially looming, I might never make that much (I hope to retire in 7 years aged 67).
Now I'm mot asking for sympathy. I made my own speculative decision and I'll do my best to find a way to make it work out for me and hopefully it will. But at least spare me the
'parasite landlords do nothing except just sit around raking it in' spiel.
Sure, there are probably better ways, some of them socialist hypotheticals, and in many cases there's excessive profiteering at the expense of those who rent, but at the same time the anti-landlord sentiment needs to be tempered. Ditto by the way for the anti-business owners/employers sentiment which breaks the surface here quite a lot. And I bet that at least some and possibly most of the white householders in the OP don't deserve to be asked to give up what they've got either. Everyone with half a brain and an education knows that capitalism and the self-initiative that goes along with it brought and brings many benefits. When it goes too far, it's a problem, yes.
