A big issue is that wealth isn't a gradual curve, its a exponential one. If someone gifted you a deposit for a house at 18 I reckon that you could compare that persons life in 20 years to someone who had the same career progression but didn't get that deposit/house and there would be hundreds of thousands of pounds difference in their wealth.
And this ******** idea that "I worked for it" needs to die a death. Most people "work for it". Thats what going to work every day is. That doesn't mean you deserve to be vastly more wealthy than someone else who didn't have the opportunities you did or the luck you did.
My partner and I are in a very privileged position in life but a large part of that has come from the fact her parents were rich and willing/able to gift her/us money towards property.
She has a house worth probably £700k that shes down to the last £100k on the mortgage. It was bought when she was at Uni with a £80k deposit I believe. She lived in it for a few years but for the last 10+ its been a rental.
They gifted us about £85k for a deposit on a flat which we paid back some of but then they basically said "don't worry about the rest". We have been paying a mortgage on a flat then house for the past 8 years I think as a couple and have turned around £100k (amount we put into flat deposit) into £350k ignoring the monthly mortgage payments we have obviously put in. We have quite aggressively overpaid the mortgages but I reckon that just from property price increases we have made around £180k.
Without her parents help there would be no house for her worth £700k and we would be in a worse house than we are now. Her parents input of around £150k has probably led to our personal wealth being around £750k higher than it would be.
Being born at the right time is important. Being born in the right place is important. Being born to the right parents is important. So much of life is chance but we all like to pretend that we have earned it and those with less haven't.
