My biggest issue with people who complain about young people is that they think young people learn negative behaviours via osmosis.

Can't blame them entirely. Competition drives down costs, and the cost is very close to free (or some of your data), or else it's some whale indirectly paying for others. Richer get richer, and some are shocked when they are priced out of big ticket items.

Older people love to talk about how they bought a house working a minimum wage job or how the janitor became CEO of the company when neither are a reality due to their greed.

Most young people are angry about the fact that their living and educational expenses are far higher than the older people responsible, and profiting from that increase. Refer also to the increase in retirement age and poorer pensions for younger generations.
