Politicians huff and puff to grab the attention of would-be supporters but at the end of the day money talks in the world of investment. If tax charges connected to the buy to let market, as one example, increase to levels which are unsustainable for investors then they will simply walk away. They will find a new market, switch their funds into that and the UK government will be left with even less social housing/private rental properties than it has today. At some point, the tail will start to wag the dog and the politicians will eventually need to listen to investors. Politicians like to think they are in control but it is investors who effectively “make markets”.
