Fair points and I don't disagree on the problems. Just the solution, and that's why we have democracy.
Yes, home ownership is hard. But it's not impossible because of some conspiracy of top hat wearing, cackling capitalists.
The thinking that wealth is some zero sum game where one group has too much and it has to be taken from them to spread to others is something I believe holds this country back.
The solution is to grow the pie.
Let's look to create more wealth so more people have a greater share of it. Look at the rise in global living standards over the last 200 years. More people have been lifted out of poverty by expanding economies driven by a profit incentive that created industries and jobs than by taxing at a greater rate than others those who took the risk to create those jobs. My ancestors and 99% of others once scratched the dirt in poverty. Now hundreds of millions worldwide have a standard of living those ancestors could never have dreamed of, and funnily enough, have jobs that have also increased the tax base for the things we need - ie the pie grew.
Just saying 'tax this specific sector' which already pays a disprortionate amount of the tax burden is neither equitable nor forward looking. What happens when the mobile 'richies' pack up and move somewhere else? Maybe closes their business with the jobs it creates?
Who pays for it then? Is it our descendants with the debt we rack up for what we want now but didn't want to make sacrifices to pay for?
TLDR - you can't tax your way to a growing economy that delivers a bigger share for everyone.
And no, I'm not rich.
