Whatever people think was the 'glory days' was propped up by unrealistically low interest rates and all other manner of things that could never have lasted.
We need to get away from this idea that life owes us anything in the UK. We're not 'owed' year on year house price increases, or foreign holidays, or multiple car ownership. People could afford those because interest rates on borrowing were low, which also meant comically easy to obtain PCP deals on cars, and lots of money to borrow for housing.
If you're genuinely struggling with food vs heating then this post is not for you - this is a horrendous time.
But for those people lamenting "life as we once knew it", go and enjoy your holiday photos and consider whether both your 17 year old son and 19 year old daughter each need cars to drive, or whether you overstretched yourself on your mortgage. We've been propped up and insulated for years from reality.
