We live on a homestead and we would want to help our kids financially (if they needed a house, for example) and create generational wealth. We are reliant on my husband's income, he works as a programmer and has good job security. But, anything can happen in 10-20 years, so it's also good to have some passive income and investments. If your job is manual labour, you'll definitely not be able to work that job forever.
I do think it's sad when boomers (with a high net worth) are going on cruise after cruise (I'm not talking about all boomers duh), and their kids are struggling. Of course these kids might be irresponsible but this describes the millenial generation, working much harder than their parents.
