The supply of lawyers isn't restricted at all, as shown by stagnant or falling median wages. Almost anyone who wants to become a lawyer can enroll in one of the "third tier toilet" private law schools, and states don't impose any limits on the number of law school graduates allowed to take the Bar exam.
The supply of lawyers is restricted through onerous education and licensing requirements. You could argue that the fall in wages means they are no longer as effective in controlling supply. But if you think the supply "isn't restricted at all" I encourage you to start offering legal advice for money and let me know how that goes for you.
I don't see anything particularly onerous about education and licensing requirements for lawyers. A sufficiently motivated student can complete law school and pass the Bar exam in a few years. So in practice there's no significant restriction on supply.

Again, if you think there are no restrictions, hang out your shingle and start giving legal advice. If you're right, you should be fine.
German labour is heavily unionized, a lot of the workers are lazy and incompetent. A lot of the union leadership is well paid and almost never works. It heavily opposes remote work(for good reason, but with a slightly wrong conclusion).
Their salary negotiations have been a clusterf* in recent years. And in fact I tried them, and contributed. But attempts at protecting employee rights were not only shut down by leadership but also fellow union leadership. They were too busy cozying up to leadership instead of protecting and informing other employees of employee rights. When it comes to employer abuse they will be too "busy" to help you, so realistically you will still need your own private law insurance.
I'm not opposed to unions and I do agree that workers need better protection especially in the US. But we also ought to be able to talk about how these big institutions may no longer protect the interest of those people and at some point exist to feed their own mouths more than the workers they were intended to protect.
Is it better than nothing? Yes, absolutely. But why do man-made structure always end up like that?
One of the fundamental asymmetries of our corporate age is that employees have ~1 company, but companies have many employees. That gives a company enormous negotiating power: it's easier for them to find another employee than for you to find another job.
Unions act to restore balance so that companies and workers have more equal negotiating power. That doesn't come through supply restriction. E.g., in high school I worked for a grocery store and we were unionized. They could have fired all the stockers at once if they wanted, as it was not particularly hard to learn the job. But what they couldn't do was pressure me into taking less money by threatening to fire me.
