No sh*t Sherlock. That's what happens when you support centrists. They pay lip service and screw everyone else for profit. There is no magic 'social democracy with capitalists'. Capitalists do what they know - sell out everyone and everything for profit, destroying the society.
So, remember to support an actual left candidate instead of centrists, fake center-left and liberals next time. So that you won't make the same mistake of sh*tting on people like Corbyn and ending up helping people like Johnson, Starmer or Biden getting the helm.
