Certainly, blaming others is an exercise in futility, even when justified, let alone when it isn't.

Having said that, it's been well established that real wages for the middle class (at least in the US) have mostly stagnated over the past 40-50 years, while the cost of housing and education both increased dramatically in real terms.

The minimum wage in the US (in real terms) actually dropped ~5% from 1970 to 2020!

A college education today is ~5x more expensive adjusting for inflation than it was in 1970 (see, e.g., https://www.intelligent.com/1970-v-2020-how-working-through-college-has-changed/).

Median home prices in the US more or less doubled since 1970 (inflation adjusted, see, e.g., https://dqydj.com/historical-home-prices/). During this time, average home size increased by 38% (see, e.g., https://www.rocketmortgage.com/learn/average-square-footage-of-a-house), so even the per-sqft cost increased 45% in real terms.
